Opis:

This work aims to confirm that the single-diode model of a monocrystalline cell can be used successfully also for thin-film solar cells when their basic parameters are calculated using the method of changing illumination. The authors describe the experimental procedure, in which I–V curves of thin-film solar cells are measured when illumination levels are changing. In experiments, a fully reflective 500 W solar simulator is used as an excellent broadband white light source, which provides the range of 0.01–10 Sun settings.

Opis:

Availability of light to solar cells is crucial for the efficiency of photovoltaic systems. For this reason, even partial shading can result in significant reduction of generated electric power (loss of current). This paper examines the changes in the efficiency of multicrystalline silicon solar cells which are caused by different kinds of shading. Full and partial shading were simulated by the use of three types of shutter-foils printed in a gray and black scale. The measurements of current-voltage characteristics show that totally or partially shaded modules can drastically reduce the generated power. Short circuit current decreases from about 8100 to 100 mA that in the case of the series connection of cells in a module, lead to the shift of the point of the maximum power and finally to the considerable reduction of nominal system photovoltaic power.

Opis:

One of the main parameters that affect the solar cell performance is cell temperature; the solar cell output decreases with the increase of temperature. Therefore, it is important to select the proper solar cell technology that performs better at a specified location considering its average temperatures. In addition, the solar cell performance is directly reflected on the overall economics of the project. This paper is proposed to evaluate the variations in the performance of different solar cell technologies related to the temperature in Amman, Jordan. Field data of weather station and three PV systems (Poly-crystalline, Mono-crystalline and Thin-film) of identical design parameters were collected from Test Field Project at Applied Science Private University, Shafa Badran, Amman, Jordan. These data were analysed in the following way. estimated specific energy yield (kWh/kWp) for the three different PV systems was calculated depending on the measured value of solar irradiance and technical specifications of the installed solar panels and inverters, then the actual energy yield at different temperatures over one year was compared with the estimated value, so the deviations could be determined and actual temperature coefficients for energy yield could be calculated, knowing that the three PV Systems have identical design parameters (tilt angle, azimuth angle, type and dimensions of mounting structure and inverter size) and same cleaning method and schedule. It was found that the thin-film solar panels are less affected by temperature with temperature coefficient of -0.0984%, and -0.109%, -0.124% for Mono-crystalline and Poly-crystalline respectively. These results can be implemented in the preliminary design steps, specifically in the selection of the solar cell technology to be installed in a specific location.

Opis:

Phosphorus ion implantation was used for the emitter formation in mono- and multicrystalline silicon solar cells. After ion implantation the silicon is strongly disordered or amorphous within the ion range. Therefore subsequent annealing is required to remove the implantation damage and activate the doping element. Flash-lamp annealing offers here an alternative route for the emitter formation at overall low thermal budget. During flash-lamp annealing, only the wafer surface is heated homogeneously to very high temperatures at ms time scales, resulting in annealing of the implantation damage and electrical activation of phosphorus. However, variation of the pulse time also allows to modify the degree of annealing of the bulk region to some extent as well, which can have an influence on the gettering behaviour of metallic bulk impurities. The μ-Raman spectroscopy showed that the silicon surface is amorphous after ion implantation. It could be demonstrated that flash-lamp annealing at 800°C for 20 ms even without preheating is sufficient to recrystallize implanted silicon. The highest carrier concentration and efficiency as well as the lowest resistivity were obtained after annealing at 1200°C for 20 ms both for mono- and multicrystalline silicon wafers. Photoluminescence results point towards P-cluster formation at high annealing temperatures which affects metal impurity gettering within the emitter.

Opis:

Zinc oxide thin films was deposited by chemical spray pyrolysis (CSP) at 400 °C substrate temperature and different thickness (60, 80, and 100) nm on the texturized p-Si wafer to fabricate ZnO/p-Si heterojunction solar cell. Structural, optical, electrical and photovoltaic properties are investigated for the samples. XRD analysis reveals that all the as deposited ZnO films show polycrystalline structure, without any change due to increase of thickness. Average diameter calculated from AFM images shows an increase in its value with increasing thickness, ranging from 59.82-95.7 nm. The optical reflections for samples are measured using UV-Vis spectrophotometer. Photoluminescence (PL) spectra of (CSP) grown ZnO/p-Si with different thickness were used to study the energy gap. The electrical properties of heterojunction were obtained by I-V (dark and illuminated) and C-V measurement. I-V characteristic of the ZnO/p-Si heterojunction shows good rectifying behavior under dark condition. The ideality factor and the saturation current density was calculated. Under illuminated the photovoltaic measurements (open-circuit voltage (Voc), short-circuit current density (JSC), fill factor (FF), and quantum efficiencies are calculated for all samples. The built- in potential (Vbi), carrier concentration and depletion width are determined under different thickness from C-V measurement.

Depleting conventional energy resources are forcing the world to search for new and renewable energy resources. Solar energy is one of the potent and abundant energy resource .To use the solar energy to its fullest along with conventional technology has specific limitations. These limitations can be eliminated by use of Dye Sensitized Solar Cell (DSSC). DSSC can be seen as promising future technology. It is advantageous over Silicon (Si) based Photovoltaic (PV) cell in terms cost, easy manufacturing, stability at higher temperature, aesthetics, etc. Also it works in indoor conditions i.e. diffused sunlight which nearly not feasible with conventional PV cells. Now Research and Development Departments of many countries like Japan, Germany, USA, Switzerland, India, China and many firms like G-Cell, Oxford PV, Sony, TATA-Dyesol are working on DSSC to improve its various aspects so as to make it more applicable in various conditions. The paper will discuss the concept, construction, working of DSSC. Also it will illustrate current applications of DSSC.

Opis:

Noise spectroscopy as a highly sensitive method for non-destructive diagnostics of semiconductor devices was applied to solar cells based on crystalline silicon with a view to evaluating the quality and reliability of this solar cell type. The experimental approach was used in a reverse-biased condition where the internal structure of solar cells, as well as pn-junction itself, was electrically stressed and overloaded by a strong electric field. This gave rise to a strong generation of a current noise accompanied by local thermal instabilities, especially in the defect sites. It turned out that local temperature changes could be correlated with generation of flicker noise in a wide frequency range. Furthermore, an electrical breakdown in a non-stable form also occurred in some specific local regions what created micro-plasma noise with a two-level current fluctuation in the form of a Lorentzian-like noise spectrum. The noise research was carried out on both of these phenomena in combination with the spectrally-filtered electroluminescence mapping in the visible/near-infrared spectrum range and the dark lock-in infrared thermography in the far-infrared range. Then the physical origin of the light emission from particular defects was searched by a scanning electron microscope and additionally there was performed an experimental elimination of one specific defect by the focused ion beam milling.

Opis:

The impact of illuminance on changes of the solar cell electromotive force is analyzed. A mathematical model for a solar cell electromotive force dependence on illuminance is presented. For this purpose, a selection of experimental data trend function was carried out, and the Pearson correlation coefficients were established. The most optimal results were obtained in case of an exponential function with the strongest correlation ($R^2$=0.983). The analysis has shown that at 100 W/m^2 illuminance the electromotive force saturation is obtained (the electromotive force changes insignificantly and fluctuates at around 2 V), which indicates that upon reaching such an illuminance a solar cell operates at maximum efficiency. A first-order differential equation satisfied by the trend function has been compiled. When interpreting illuminance as an evolution variable, the proposed mathematical model can be interpreted as a dynamical system. The deviation frequency spectrum of the measurement values with respect to the theoretical prediction is analyzed.

The films were characterized by the measurement of XRD, FTIR spectroscopy and atomic force microscopy properties (AFM). We have estimated crystallites size from X-Ray diffraction about nanoscale for porous silicon and Atomic Force microscopy confirms the nanometric size Chemical fictionalization during the electrochemical etching show on the surface chemical composition of PS. The etching possesses inhomogeneous microstructures that contain a-Si clusters (Si3–Si–H) dispersed in amorphous silica matrix. From the FTIR analyses showed that the Si dangling bonds of the as-prepared PS layer have large amount of Hydrogen to form weak Si–H bonds. The atomic force microscopy investigation shows the rough silicon surface, with increasing etching process (current density and etching time) porous structure nucleates which leads to an increase in the depth and width (diameter) of surface pits. Consequently, the surface roughness also increase.

Opis:

In this paper, the structure of a high-efficiency solar cell is presented by using a combination of quantum dots of germanium arrays and silicon nanowires on a thin film silicon layer. Due to the low absorption coefficient of silicon, this type of solar cell does not have high efficiency. According to the capability of the quantum structure in absorbing the incident photons and the generation of electron-hole pairs, this structure is proposed. Moreover, nanowires as an appropriate suggestion are applied in our work aiming to improve light scattering and optical photon absorption for the generation of carriers. Both of the electrical and optical characteristics of the solar cell are calculated by using a finite-difference time-domain method. Owing to the change of the nanowire length and increasing the number of quantum dot in our work, maximum power absorption is achieved. The achieved results provide a considerable improvement in efficiency and short-circuit current density. The efficiency is improved up to 17.5% and the short-circuit current density in the active layer of thickness 1170 nm has been provided to be 42.6 mA/cm². The open circuit voltage for this cell is calculated to be 0.47 V. The achieved results provide a considerable improvement in efficiency and short-circuit current density in comparison with previously published method.

The increasing concern for worldwide energy production is the result of global industrialization and decreasing energy resources. Despite the cost factor, solar energy continues to become more popular due to its long-term nature as a resource and growing conversion efficiency. A dye-sensitized solar cell converts visible light into electricity. The efficient use of dye as a sensitizer is the critical factor in enhancing the performance of the dye-sensitized solar cell. Natural dyes are found in abundance in leaves, flower petals, roots, and other natural resources. Due to the advantages of natural dyes such as cost-effectiveness, the simpler extraction process, and being environmentally friendly, etc., researchers are working extensively to replace synthetic dyes with natural ones. This paper highlights the various types of natural dyes and their effect on the efficiency of the dye-sensitized solar cell.

The geometries, electronic structures, polarizabilities and hyperpolarizabilities of organic dye sensitizer 4-methoxybenzonitrile was studied based on ab initio HF and Density Functional Theory (DFT) using the hybrid functional B3LYP. Ultraviolet-visible (UV-Vis) spectrum was investigated by Time Dependent DFT (TDDFT). Features of the electronic absorption spectrum in the visible and near-UV regions were assigned based on TDDFT calculations. The absorption bands are assigned to π→π* transitions. Calculated results suggest that the three excited states with the lowest excited energies in 4-methoxybenzonitrile is due to photoinduced electron transfer processes. The interfacial electron transfer between semiconductor TiO2 electrode and dye sensitizer 4-methoxybenzonitrile, is due to an electron injection process from excited dye to the semiconductor’s conduction band. The role of nitro group in 4-methoxybenzonitrile in geometries, electronic structures, and spectral properties were analyzed.

Opis:

This study examines the optimal parameters for obtaining fluorine-doped SnO2 (FTO) films with promising potential for photovoltaic applications. Due to its properties, tin oxide is used in a wide range of technologies, among which the manufacture of solar cells is one of the most important. Being doped with fluorine, tin dioxide becomes a good transparent and conductive electrode, suitable for solar cell applications. The chemical stability and low cost of the doped SnO2 makes it an advantageous alternative to tin-doped indium oxide (ITO). Among the most important characteristics of FTO thin films are high photoconductivity under sunlight irradiation and strong UV absorption. The SnO2 compound, doped with fluorine, exhibits a considerable chemical and physical stability, good electrical conductivity and high transmission (over 85%) in the visible range. The spray pyrolysis technique is the most preferable and efficient deposition method of fluorine-doped SnO2 thin films.

Opis:

The nanoparticles of CH₃NH₃PbBr₃ hybrid perovskites were synthesized. These perovskite nanoparticles we embedded in polymethyl methacrylate (PMMA) in order to obtain the composite, which we used as light converter for silicon solar cells. It was shown that the composite emit the light with the intensity maximum at about 527 nm when exited by a short wavelength (300÷450 nm) of light. The silicon solar cells were used to examine the effect of down-conversion (DC) process by perovskite nanoparticles embedded in PMMA. For experiments, two groups of monocrystalline silicon solar cells were used. The first one included the solar cells without surface texturization and antireflection coating. The second one included the commercial cells with surface texturization and antireflection coating. In every series of the cells one part of the cells were covered by composite (CH₃NH₃PbBr₃ in PMMA) layer and second part of cells by pure PMMA for comparison. It was shown that External Quantum Efficiency EQE of the photovoltaic cells covered by composite (CH₃NH₃PbBr₃ in PMMA) layer was improved in both group of the cells but unfortunately the Internal Quantum Efficiency was reduced. This reduction was caused by high absorption of the short wavelength light and reabsorption of the luminescence light. Therefore, the CH₃NH₃PbBr₃ perovskite nanoparticles embedded in PMMA matrix were unable to increase silicon solar cell efficiency in the tested systems.

Opis:

In this paper, we have proposed dye-sensitized hybrid solar cell based on $TiO_2$ nanoparticles as a medium for electron transport and conjugated polymers as hole-conductor, where dye molecules absorb solar radiation and create electron-hole pairs. This solar cell can be a better alternative to conventional electrolyte based dye-sensitized solar cells, because of enhanced characteristics of performance. We have simulated it numerically, to study essential characteristics of the structure such as electron, hole and their current densities and internal electric field in two operating conditions of open-circuit and short-circuit cases. Then current-voltage characteristic diagram has been plotted and energy conversion efficiency calculated.

Opis:

The paper presents a dual-band plasmonic solar cell. The proposed unit structure gathers two layers, each layer consists of a silver nanoparticle deposited on a GaAs substrate and covered with an ITO layer, It reveals two discrete absorption bands in the infra-red part of the solar spectrum. Nanoparticle structures have been used for light-trapping to increase the absorption of plasmonic solar cells. By proper engineering of these structures, resonance frequencies and absorption coefficients can be controlled as it will be elucidated. The simulation results are achieved using CST Microwave Studio through the finite element method. The results indicate that this proposed dual-band plasmonic solar cell exhibits an absorption bandwidth, defined as the full width at half maximum, reaches 71 nm. Moreover, It can be noticed that by controlling the nanoparticle height above the GaAs substrate, the absorption peak can be increased to reach 0.77.

Opis:

GZO/IZO semiconductor thin films were prepared on the ITO substrate via sol-gel spin coating method for using in the dye-sensitized solar cells (DSSCs). For this purpose, GZO and IZO thin films were optimized by the percentage of doping gallium and indium in zinc oxide and were studied their electrical, optical and structural properties. After that, the layers with the best performance were selected for use in the DSSCs. The concentration of all solutions for spin coating processes was 0.1 M and zinc oxide has been doped with gallium and indium, with different doping percentages (0, 0.5, 1, 2 and 4 volume percentage). So, by studying the properties of the fabricated thin films, it was found the films with 0.5%GZO and 0.5%IZO have the best performance and hence, the optimized dual-layer (0.5% GZO/0.5% IZO (GIZO)) were prepared and studied their electrical and optical properties. The synthesized optimized dual-layer film was successfully used as the working electrode for dye-sensitized solar cells. The sample with 0.5%IZO shows the 9.1 mA/cm² short-circuit current density, 0.52 V open circuit voltage, 63% fill factor and 2.98% efficiency.

Opis:

Na podstawie dokonanego przeglądu literatury i badań własnych przedstawiono różne rodzaje ogniw słonecznych stosowanych w fotowoltaice organicznej. Prace badawcze dotyczące rozwoju fotowoltaiki organicznej prowadzone są obecnie w trzech głównych kierunkach: (i) poszukiwanie nowych polimerów, jak też związków małocząsteczkowych stosowanych jako warstwa aktywna ogniwa fotowoltaicznego, (ii) modyfikacja architektury ogniwa słonecznego oraz (iii) udoskonalanie metod wytwarzania poszczególnych warstw w ogniwie. W IEL Wrocław (Pracownia Nowych Technologii) prowadzone są prace nad ogniwami fotowoltaicznymi organicznymi zarówno warstwowymi jak i objętościowymi (bulk heterojunction, BHJ). Istotną część prac Pracowni Nowych Technologii zajmują badania nad optymalizacją struktury stosowanych materiałów organicznych, w tym związków mało- i wielkocząsteczkowych w fotowoltaice organicznej. W niniejszej pracy warstwa aktywna badanych ogniw fotowoltaicznych składała się z materiału o charakterze donorowym (poli(3-heksylotiofen), P3HT lub poliazometiny) i akceptorowym (ester metylowy kwasu [6,6]fenylo-C61-masłowego, PCBM). Skonstruowano ogniwa fotowoltaiczne ITO/PEDOT:PSS/P3HT:PCBM/Al oraz ogniwa odniesienia i wyznaczono dla nich charakterystyki prądowo-napięciowe przy zastosowaniu jako źródła światła lampy ksenonowej. Do pomiarów wykorzystano urządzenie Solartron Model 1287A potentiostat/galwanostat za pomocą, którego określono parametry fotowoltaiczne badanych ogniw. Wykazano wpływ budowy polimeru i architektury ogniwa na wartości parametrów fotowoltaicznych tj. sprawność (PCE), współczynnik wypełnienia (FF) czy też napięcie rozwarcia (Voc) i prąd zwarcia ogniwa (Jsc). Najwyższą wartość sprawności fotowoltaicznej, jaką dotychczas otrzymano w IEL Wrocław, określono na poziomie 2,4% dla ogniwa polimerowego objętościowego. Konstrukcja ogniwa była wykonywana w warunkach laboratoryjnych w atmosferze powietrza.
In this work based on the literature and own research different kinds of organic solar cells are presented. Research works concerning the development of organic photovoltaics are at present in three main directions: (i) the synthesis of new polymers and small compounds as the active layer of the solar cells, (ii) the modification of the architecture of the solar cells and (iii) perfecting of methods of the production of each layers in the solar cells. IEL Wrocław (the Lab of New Technologies) specializes in works over organic photovoltaics with both bilayers and bulk heterojunction, BHJ solar cells. Led are also researches over the optimization of the structure of organic materials including small- and high-molecular compounds in organic photovoltaics. In the present work the active layer of investigated solar cells consisted of the donor (poly(3-hexylthiophene-2,5-diyl), P3HT or polyazomethines) and the acceptor material ([6,6]-phenyl-C61-butyric acid methyl ester, PCBM). Organic photovoltaic devices with the configuration of ITO/PEDOT:PSS/P3HT:PCBM and reference solar cells were investigated under an illumination of 100 mW/cm2 (xenon lamp) with an AM1.5G by applied Solartron the Model 1287A potentiostat/the galvanostat. One showed the influence of the chemical structure of the polymers and the architecture of the solar cells on the value of photovoltaic parameters i.e. the power conversion efficiency (PCE), the fill factor (FF) or else the open circuit voltage (Voc) and the short circuit current (Jsc). The highest value of the PCE, which till now one received in IEL Wrocław, one qualified on level 2.4% for the BHJ polymer solar cell. The construction of the solar cells was performed conditioned of laboratory in the air atmosphere.

Opis:

W artykule przedstawione zostały rezultaty symulacji lateralnego wzrostu epitaksjalnego (ELO – Epitaxial Lateral Overgrowth) przeprowadzonych dla krzemowych podłoży wzrostowych o różnych współczynnikach wypełnienia maski (mask-to-window ratio): 70%, 50%, 30% oraz 10%. Zastosowano przy tym następujące parametry: wymiary domeny: 1000 µm × 2000 µm, szybkość chłodzenia: 0,5ºC/min, temperatura początkowa: 920ºC. Przedstawiono przykładową domenę obliczeniową oraz wygenerowaną siatkę numeryczną. W celu zwiększenia precyzji obliczeń w obszarach dużych gradientów koncentracji zastosowano zagęszczenie siatki. Dla wybranych geometrii domen przedstawiono profile koncentracji. Zbadano wpływ geometrii obszaru na kształt pola koncentracji, określającego strumienie masy. Zwiększenie powierzchni krystalizacji składnika spowodowało ukształtowanie się linii stałej koncentracji w objętości roztworu, charakterystyczne dla standardowej metody LPE. Kierunek przepływu Si w objętości jest prostopadły do powierzchni podłoża na całej jego długości. Natomiast przy powierzchni podłoża, na stosunkowo niewielkiej odległości, tworzy się warstwa roztworu, w której linie stałej koncentracji układają się wokół okien Si. Grubość tej warstwy zależy od stopnia wypełnienia i maleje wraz ze wzrostem liczby okien w obszarze domeny. Sąsiadujące ze sobą okna stanowią dla siebie konkurencję pod względem obszaru krystalizacji: tym większą, im bliżej siebie są umiejscowione. Przyczynia się to bezpośrednio do zmniejszenia szybkości wzrostu w kierunku lateralnym przy niewielkiej zmianie wartości szybkości w kierunku normalnym. Skutkuje to również zmniejszeniem wydłużenia względnego otrzymywanych warstw. Z analiz numerycznych wynika, że w celu otrzymania warstw lateralnych o maksymalnym wydłużeniu względnym należy uwzględnić szerokość pasm dielektryka znajdującego się między oknami. Odpowiednie dobranie geometrii podłoża pozwala na uzyskanie możliwie maksymalnych szybkości wzrostu w kierunku lateralnym.

Opis:

The geometries, electronic structures, polarizabilities, and hyperpolarizabilities of natural dye sensitizer alizarin from madder fruit was studied based on density functional theory using the hybrid functional B3LYP. Features of the electronic absorption spectra in the visible and near-UV regions were assigned based on time-dependent density function theory calculations. The calculated results suggest three excited states with the lowest excited energies in 1,2-dihydroxy-9,10-anthraquinone and it was due to photoinduced electron transfer processes. The interfacial electron transfer between semiconductor $TiO_2$ electrode and dye sensitizer 1,2-dihydroxy-9,10-anthraquinone is due to an electron injection process from excited dye to the semiconductor conduction band. The importance of hydroxyl group in geometries, electronic structures and spectral properties were reported.

Opis:

The simulation analysis was performed to enhance the efficiency of Sb2 S3 solar cells using the SCAPS-1D software. The Sb2 S3 compound was used as the absorber layer in the solar cell. The simulation was conducted to verify the efficiency and accuracy of the results obtained from the program. The results were found to be in agreement with the practical results. The original cell’s efficiency was 11.47% with a fill factor of 61.18%, and after the simulation, the efficiency was found to be 11.43% with a fill factor of 61.2%. To enhance the efficiency of the solar cell, a reflective background layer (BSL) was added. Different BSL layers were examined, including SnS, Si, CIGS, CZTSSe, and CUS bS3 , and the best reflective layer was found to be CUSbS3 . The solar cell structure was designed as follows: glass/Mo/CUSbS3 /Sb2 S3 /CdS/i:ZnO/AL:ZnO. After adding the reflective layer, the efficiency of the solar cell was found to be 20.59% with a fill factor of 87.53%. The results suggest that adding reflective layers to solar cells can enhance their performance and increase their efficiency.

In the present work, the fabrication and characterization of non-curling, free-standing $TiO_2$ nanotube membranes and their integration in front-side illuminated dye-sensitized solar cells are reported. Vertically oriented $TiO_2$ nanotube arrays were fabricated by anodic oxidation of a titanium foil. Nanotube membranes were detached from the metallic foil, transferred and bonded on transparent fluorine-doped tin oxide/glass substrates employing a $TiO_2$ sol as a binder. Crystalline phase and morphology of the film were investigated, evidencing the formation of a highly ordered 1D nanotubes carpet, with a pure anatase crystalline structure. $TiO_2$ nanotube-based DSCs were fabricated using reversible microfluidic architecture. The cell performances were studied by I-V electrical characterization, incident-photon-to-electron conversion efficiency, electrochemical impedance spectroscopy and open circuit voltage decay measurements, showing an increase in electron lifetime compared to nanoparticle-based dye-sensitized solar cells.

Opis:

Single crystalline cesium doped ZnO nanorods with homogeneous size and shape were grown hydrothermally on ITO substrates that are presented in our previous work. According to the previous work, XRD analysis showed that cesium doped ZnO nanorods are wurtzite single crystals and are grown preferentially along the c-axis. Also, the electrical conductivity of doped ZnO showed higher values for the 1% cesium, which confirmed incorporation of the cesium dopant. Cesium doped ZnO nanorods are suitable candidates for applications in solar cells. So, in this research, we employed cesium doped ZnO nanorods with the different dopant concentration in inverted polymer solar cell. By comparing the effect of doped ZnO nanorods with diverse dopant concentration (0, 0.5, 1.0, 1.5 and 2%) on the performance of devices, 1.0% cesium doped ZnO was found as the most effective doping level among the selected doping concentrations. Also, using 1.0% cesium doped ZnO nanorods, Jsc of 8.21 mA/cm², Voc of 0.541V and Fill Factor of 63.01% were achieved, which led to power conversion efficiency of 2.80%.

Opis:

This work put in evidence, magnetic field effect the electrical parameters of a silicon solar cell illuminated by an intense light concentration: external load electric power, conversion efficiency, fill factor, external optimal charge load. Due to the high photogeneration of a carrier in intense light illumination mode, in addition of magnetic field, we took into account the carrier gradient electric field in the base of the solar cell. Taking into account this electric field and the applied magnetic field in our model led to new analytical expressions of the continuity equation, the photocurrent and the photovoltage. In this work, we used the electric power curves versus junction dynamic velocity (Sj) to determine, according to magnetic field, the maximum electric power Pelmax and we calculate the solar cell conversion efficiency (η). We also used the J-V characteristics to determine the solar cell short circuit density current (Jcc) and the open circuit voltage (Vco) under magnetic field and we calculate the fill factor (FF). Finally, we used simultaneously the J-V characteristics and equipower curves to determine the optimal external load resistance. The results of this study have showed that the maximum electric power and the conversion efficiency are higher than those of monofacial and bifacial silicon solar cells illuminated by conventional light but they decreased with the increase of magnetic field.

Opis:

High-resolution X-ray diffractometer was used to study structural quality, lattice parameters and misfit strain in p-ZnTe/n-CdTe heterojunctions grown by the molecular-beam epitaxy technique on two different (001)-oriented substrates of GaAs and CdTe. The X-ray diffractometer results indicate that the CdTe layers, grown on lattice mismatched GaAs substrate, are partially relaxed, by the formation of misfit dislocations at the interface, and display residual vertical strain of the order of $10^{-4}$. The presence of threading dislocations in the layers effectively limits the efficiency of solar energy conversion in the investigated heterojunctions. Homoepitaxially grown CdTe layers, of much better structural quality, display unexpected compressive strain in the layers and the relaxed lattice parameter larger than that of the substrate. Possible reasons for the formation of that unusual strain are discussed.

Opis:

Solar cells are not only environmentally friendly, but save considerable electricity costs as well (namely, in this case, only maintenance costs have to be paid, the value of which is significantly lower than the price of electricity). The long term aim is for these energy sources to be applied and used by all macroeconomic actors (companies, households, the government and other institutions). Such cells can be introduced by applying for a considerable amount of investment subsidies at an EU level and in Hungary, as well. However, the ROI of this kind of undertaking is long term. The aim of this study is to examine whether a non-profit public institution would find it worthwhile to invest in this type of venture in the long term. Thus, the ROI of a solar cell investment was examined at a well-known environmentally public institution, at an abbey in Hungary. Data were provided by the abbey. From available data, ROI calculations were carried out and the approximate payback period was estimated. Calculations were carried out taking into account different scenarios. One part of the research focused on the inflation rate (there was a case where the inflation rate was ignored), in the other part, the cost of investment was taking into account in different ways. The payback period of solar cell investment is relatively short (11-13 years) in the case of EU or government subsidies, otherwise it is quite long (25-30 years).
Ogniwa słoneczne są nie tylko przyjazne dla środowiska, ale również pozwalają na uzyskanie znacznych oszczędności kosztów elektryczności (w tym przypadku bowiem ponoszone są jedynie koszty konserwacji, które są znacząco niższe od cen elektryczności). Celem długoterminowym jest wdrożenie i korzystanie z tych źródeł energii przez wszystkie podmioty rynkowe w ujęciu makroekonomicznym (spółki, gospodarstwa domowe, instytucje rządowe i inne). Tego rodzaju ogniwa mogą również być wprowadzane do użytku przez składanie wniosków o udzielenie znacznego dofinansowania inwestycji do UE lub do węgierskiego rządu. Celem opracowania jest ocena, czy instytucja publiczna typu non-profit uznałaby za godną uwagi inwestycję w ten rodzaj przedsięwzięcia w ujęciu długoterminowym. Zwrot z inwestycji w ogniwa słoneczne zbadano na przykładzie węgierskiego opactwa, instytucji publicznej znanej z zaangażowania w kwestie ochrony środowiska. Wszelkie dane zostały udostępnione przez opactwo. Na podstawie tych danych obliczono zwrot z inwestycji oraz oszacowano przybliżony okres zwrotu. Obliczeń dokonano z uwzględnieniem różnych scenariuszy. Skupiono się na stopie inflacji (istniał również przypadek, w którym stopa inflacji nie została wzięta pod uwagę), a także uwzględniono różne podejścia do kosztu inwestycji. Okres zwrotu z inwestycji w ogniwa słoneczne jest stosunkowo krótki (11-13 lat) w przypadku uzyskania unijnego lub rządowego dofinansowania. W przeciwnym razie jest on dużo dłuższy (25-30 lat).

Opis:

Multicrystalline and monocrystalline silicon solar cells are the most popular for commercial applications. Numerous material parameters could affect solar cell performance. The application of antireflective coatings of amorphous silicon based alloys can increase device efficiency. Such coatings due to tunable energy gap and refractive index and non-expensive fabrication method - Plasma Enhanced Chemical Vapour Deposition at 13.56 MHz are good candidates for large scale application. The authors presented the influence of material properties of bulk cell on solar cell efficiency by the use of computer PC-ID simulation program, which solves the fully coupled nonlinear equations for the quasi-one-dimensional transport of electrons and holes in crystalline devices, with emphasis on photovoltaic devices. The temperature, series and shunt resistance, recombination velocity and wafer thickness have the influence on current--voltage photo-characteristics of solar cells and their efficiency. Also the influence of thickness, reflective coefficient and refractive index of antireflective coatings on solar cells performance was examined. The optimal parameters of efficient solar cell were determined.
Światowa produkcja ogniw słonecznych opiera się przede wszystkim na krzemie mono- i multikrystalicznym. Właściwości materiałowe istotnie wpływają na jakość, a przede wszystkim na ich parametry użytkowe. Wydatny wzrost sprawności ogniw można uzyskać poprzez zastosowanie warstw ARC. Tego typu powłoki, z możliwością optymalizacji współczynnika załamania oraz przerwy optycznej, można otrzymywać metodami Chemicznego Osadzania z Fazy Gazowej (RFCVD - Radio Frequency Chemical Vapour Depositiori). Autorzy zbadali wpływ właściwości materiałowych na sprawność ogniw korzystając z metody numerycznej - program PC-1D. Program umożliwia wyznaczenie końcowych parametrów ogniw z uwzględnieniem zarówno stałych materiałowych podłoża, jak i elementów modyfikujących to ogniwo. Na kształt charakterystyki prądowo-napięciowej I-V (model dwudiodowy) i sprawność ogniwa mają wpływ: temperatura, rezystancja szeregowa i zwierająca, szybkość rekombinacji oraz grubość podłoża. W przypadku warstw antyrefleksyjnych, decydujące są: grubość, współczynnik załamania oraz współczynnik odbicia. Program symulacyjny pozwolił określić optymalne parametry wydajnych ogniw słonecznych na bazie krzemu, z uwzględnieniem bardzo istotnego wpływu warstw ARC.

Opis:

This paper studies the environmental impact of two different forms of solar power generation in Thailand – that of multicrystalline silicon solar cells, and that of thin film amorphous silicon solar cells. It takes as its study two of the largest solar cell power plants of their kind in Thailand; a multicrystalline silicon plant in the north (generating 90 MW) and a thin film amorphous silicon plant in the centre (generating 55 MW). The Life Cycle Assessment tool (LCA) was used to assess the environmental impact of each stage of the process, from the manufacture of the cells, through to their transportation, installation and eventual recycling. The functional unit of the study was the generation of 1 kWh of power transmitted and distributed by the Electricity Generating Authority of Thailand (EGAT) and Provincial Electricity Authority (PEA). The environmental impact results were calculated in terms of eco-points (Pt) per functional unit of 1 kWh. The characterised data for 1 kWh of solar power generation was then compared with data for 1 kWh of combined cycle and thermal power generation (both in Thailand), using the same set of characterisation factors. After analyzing the results, both forms of solar power energy generation were found to impact upon the studied categories of Human Health, Ecosystem Quality and Resource Depletion, whilst also highlighting the importance of the solar cell module recycling process in decreasing the overall environmental impact. When the two solar cell technologies were compared, the overall impact of the multicrystalline silicon solar cell was found to be higher than that of the thin film amorphous silicon solar cell. Furthermore, when assessing the overall impact against non-renewable power generating technologies such as combined cycle and thermal power generation, the thin film amorphous silicon solar cells were found to have the lowest environmental impact of all technologies studied.

Opis:

This paper presents research on the deposition of an indium tin oxide (ITO) layer which may act as a recombination layer in a silicon/perovskite tandem solar cell. ITO was deposited by magnetron sputtering on a highly porous surface of silicon etched by the metal-assisted etching method (MAE) for texturing as nano and microwires. The homogeneity of the ITO layer and the degree of coverage of the silicon wires were assessed using electron microscopy imaging techniques. The quality of the deposited layer was specified, and problems related to both the presence of a porous substrate and the deposition method were determined. The presence of a characteristic structure of the deposited ITO layer resembling a "match" in shape was demonstrated. Due to the specificity of the porous layer of silicon wires, the ITO layer should not exceed 80 nm. Additionally, to avoid differences in ITO thickness at the top and base of the silicon wire, the layer should be no thicker than 40 nm for the given deposition parameters.

Opis:

This paper presents the investigations and performance analysis of monofacial and bifacial crystalline silicon solar cells with PC1D simulation software. The fundamental limitation in the monofacial solar cell’s performance is its inability to absorb all the incoming solar radiation since the albedo effect (ground-reflected light that can be captured by the rear of the solar cell) is often neglected. So, the efficiency of the monofacial cell will be lower due to poor and incomplete optical absorption. Bifaciality helps to enhance the capturing of light in the solar cell, which means that the rear of the cell is exposed to solar radiation to produce electrical power. The primary focus of our work is to determine which solar cell offers better device performance and conversion efficiency by analyzing various parameters of the solar cell like surface texturing, emitter doping, bulk doping, minority carrier lifetime, bulk and surface recombination rates, front and rear reflectance, among other parameters. The other parameters are maintained at an optimal range to achieve the highest conversion efficiency. Our work has shown that the bifacial solar cell can be as efficient as 28.15%, which is much better than the 22.65% efficiency of the monofacial solar cell.

Opis:

The basic objective in photovoltaics is obtaining electrical energy with the costs comparable to the costs of energy obtained from conventional fuels. The effectiveness of acquisition of electrical energy from solar cells can be improved, among other things, by using solar radiation concentrators. Photovoltaic systems with low concentration (LCPV) and high concentration (HCPV) were characterised [13]. The possibilities of their operation under various conditions were presented, whereas the impact of temperature and concentration angle were considered in particular. The most modern solutions were presented, including Spin cell, Ephocell, Interdigitated Back Contact (IBC), Luminescent Solar Concentrator (LSC), High Concentration PhotoVoltaic Thermal (HCPVT), Concentration PhotoVoltaic (CPV), Telecontrolli. Results of current Polish research were given. In the years from 1985 to 2010 the increase from 17,5 % to 40,7 % in the efficiency of solar cells with concentrators was achieved [18].

Dye sensitized solar cell (DSSC) shows great promise as an alternative to conventional p-n junction solar cells due to their low fabrication cost and reasonably high efficiency. DSSC was assembled by using natural dye extracted from red amaranth (Amaranthus Gangeticus) as a sensitizer and different catalysts for counter electrode were applied for maximum energy conversion efficiency. Annealing temperature and thickness of electrode were also investigated and optimized. Catalyst, annealing temperature and thickness were optimized by the determination of cell performance considering photoelectrochemical output and measuring current and voltage; then calculating efficiency and other electrical parameters. The experimental results indicated that samples having 40 μm electrode thickness and prepared at 450 ^o C annealing temperature showed the best performance.

In perovskite solar cells, series of symmetrical and asymmetrical imino-naphthalimides were tested as hole-transporting materials. The compounds exhibited high thermal stability at the temperature of the beginning of thermal decomposition above 300 °C. Obtained imino-naphthalimides were electrochemically active and their adequate energy levels confirm the application possibility in the perovskite solar cells. Imino-naphthalimides were absorbed with the maximum wavelength in the range from 331 nm to 411 nm and emitted light from the blue spectral region in a chloroform solution. The presented materials were tested in the perovskite solar cells devices with a construction of FTO/b-TiO2/m-TiO2/perovskite/ HTM/Au. For comparison, the reference perovskite cells were also performed (without hole-transporting materials layer). Of all the proposed materials tested as hole-transporting materials, the bis-(imino-naphthalimide) containing in core the triphenylamine structure showed a power conversion efficiency at 1.10% with a short-circuit current at 1.86 mA and an open-circuit voltage at 581 mV.

Opis:

The influence of a p-type Si with different resistivity, charge carrier lifetime and emitter dopant impurities concentration on the crystalline silicon solar cells parameters were analyzed and experimentally checked. The findings were determined by quasi-steady-state photoconductance, current-voltage and spectral response methods. The study was accompanied by solar device simulation using a numerical PC1D program. The highest photoconversion efficiency of 15.13 % was obtained for the moncrystalline (Cz-Si) solar cell with a base resistivity of 1.8 Ωcm and an effective charge carrier lifetime of 22.9 μs. The results clearly confirmed the importance concerning the dopant level in a Si base material in relation to open circuit voltage and short circuit current possible to obtain from the solar cell. Reduction of a base material resistivtiy leads to a lower value of an effective charge carrier lifetime and photoconversion efficiency both for Cz-Si and multicrystalline (mc-Si) solar cells. The experimental results and calculation showed, that in the case of a solar cell produced on the basis of crystalline silicon, the most important spectral range for an efficiency of a cell is covering a wavelength range of 587 ÷ 838 nm.

For this process, the optimum refractive index and its corresponding available material which can be used as the grating material has been chosen as 1.57 and SiO₂, respectively. Also, all of geometric parameters which affect the performance of the grating, such as periodicity, height and depth of grating profiles have been studied and the appropriate values for each of them have been proposed. In order to optimize the profile of grating, a transition from triangular to rectangular structure has been considered and finally a specific trapezoidal profile has been chosen as the optimized grating back reflector which enhances the cell efficiency up to 6%. Simulation results show that the different grating profiles have the same duty cycle and therefore use the same amounts of materials.

Opis:

The properties and the efficiency of a semiconductor thin film depend on the state of stress and defects in the film structure. When the film is growing layer by layer, the elastic energy due to deformation stress between the substrate and the film is released partly due to the formation of dislocations in the critical thickness deformation. In this paper, we present a finite element analysis of the stress state in a thin film of $Cu_3BiS_3$ as a function of thickness and elastic energy release by nucleation of dislocations. Initially, we analyze the stress contours associated with the epitaxial growth and dislocation nucleation and then combine these two in order to study the effective potential energy state of the system. Finally, the tool wxAMPS is today an important application for simulation of solar cells with high reliability and an improved design over its analysis of microelectronic and photonic structures predecessor, incorporating physical principles concerning photovoltaic phenomena and uses a new method for solving algorithms, combining Newton and Gummel approaches, which provides greater stability and speed of computation.

Opis:

In this work we present simple non-destructive method for extracting of Cu(In,Ga)(S,Se)2-based solar cell parameters (space-charge region width and diffusion length of minority charge carriers in Cu(In,Ga)(S,Se)2 absorber) from the analysis of solar cell spectral characteristics. This method is based on one-dimensional model of a solar cell when the change of in-depth distribution of the photogenerated carriers and, hence, the change of its photoresponse with the variation of excitation wave-length in solar cell is taking into account. The following assumptions are accepted: the reflection of charge carriers from back contact and the «drawing» fields in the quasi-neutral area of the absorber layers are negligible; window and buffer layers are transparent in the analyzed of spectrum range; the injection level of minority charge carriers is low; the recombination losses at the metallurgical p-n-junction interface of the studied photosensitive structure are dependent linearly on the photocurrent density.
W pracy przedstawiono prostą metodę nieniszczącego wyznaczenia parametrów (szerokość obszaru ładunku przestrzennego i długość drogi dyfuzji mniejszościowych nośników ładunku w absorberze) dla ogniw słonecznych na bazie Cu(In,Ga)(S, Se)2 z analizy charakterystyk widmowych ogniw słonecznych. Metoda opiera się na jednowymiarowym modelu ogniwa słonecznego, kiedy zmiana rozkładu generowanych optycznie nośników jest prostopadła do powierzchni i zmiana fotoodpowiedzi ze zmianą długości fali światła wzbudzającego jest brana pod uwagę. Przyjęto poniższe założenia: odbicie nośników ładunku od tylnego kontaktu oraz zmiana pola profilu w okolicy quasi-neutralne warstw absorbera są nieistotne; warstwy czołowa i buforowa są przezroczyste w analizowanym zakresie widmowym; poziom generacji mniejszościowych nośników ładunku jest niski; straty rekombinacyjne w bazowym n-p złączu badanej struktury są uzależnione światłoczułych liniowo od gęstości fotoprądu.

Opis:

In this study titanium dioxide nanopowder has been manufactured and examined. Nanocrystalline TiO₂ powder has been obtained by hydrolysis and peptization of a solution of titanium isopropoxide and isopropanol. Subsequently, produced powder has been subjected to structural analysis by using a transmission electron microscope, X-ray diffractometer, and Raman spectrometer. For comparison purposes, a commercially available titanium dioxide powder (i.e. titanium white) was also used. Thin layers have been made from this powder and further have been examined by using a UV/VIS spectrometer. Completed research shows the nanocrystalline structure of obtained layers and their good properties such as absorbance at the range of wavelength equal 200 - 1000 nm.

Opis:

Fast and effective extraction of equivalent shunt resistance for each subcell of GaInP/GaInAs/Ge triple-junction concentrator solar cells is presented. The two-diode model of single junction was introduced to establish the equivalent circuit of triple-junction solar cells. The current-voltage characteristic of the triple-junction solar cells was measured under AM1.5D spectrum, C = 576 and T = 303 K. Equivalent shunt resistance of each subcell was extracted from its estimated current-voltage curve. The estimated current-voltage curve of the triple-junction solar cells shows a good agreement with the experimental data in 0.31% deviation. The degradation in the equivalent shunt resistance for Ge subcell was intentionally introduced to indicate the mechanism of current-matching operation for different subcells, with the maximum output power of the triple-junction solar cells deteriorating from 3.5 to 3.17 W. The results can offer performance analysis and optimum design of photovoltaic applications.

Opis:

Praca skupia się na badaniu wpływu zmian temperatury zewnętrznej oraz stopnia zacienienia powierzchni ogniw słonecznych na ich parametry elektryczne. Charakterystyki prądowo-napięciowe I-V ogniw słonecznych na bazie krzemu multikrystalicznego były wyznaczone przy oświetleniu AM 1.5 za pomocą urządzenia sterowanego komputerowo I-V Curve Tracer For Solar Cells Qualification. Poprzez zastosowanie elektrycznego modelu dwudiodowego, pomiary charakterystyk I-V ogniw pozwoliły określić sprawność ogniw oraz ich prąd zwarcia i napięcie obwodu otwartego. Pomiary temperaturowe przeprowadzono w zakresie od 5 do 55 °C, przy stałym i równomiernym oświetleniu całej powierzchni ogniw. Zmienny stopień zacienienia powierzchni ogniw miał bardzo istotny wpływ na ich parametry elektryczne. Obniżenie sprawności ogniw słonecznych wraz z temperaturą oraz stopniem zacienienia jest czynnikiem bardzo istotnym przy optymalizacji warunków pracy systemów fotowoltaicznych.
The purpose of the work is the investigation of influence of rapid change of temperature and the shadowing of light on silicon solar cells operation. Current-voltage characteristics for multicrystalline silicon solar cells were measured by the use of computer controlled global spectrum sun simulator under an AM 1.5. The measurements of I-V characteristics allow the determination of basic electrical parameters and efficiency using the double exponential relationship from two-diode solar cells model. Temperature measurements were carried out in the temperature range from 5 to 55 °C under constant irradiance. Under changeable area of illumination of solar cells was also observed the variation of their parameters. The rate of decrease of solar cells efficiency with temperature and shadowing area are important to estimate optimal working conditions of PV systems.

Opis:

In this work, a one dimensional approach is presented for modelling the effect of the incidence angle, varying from 0 rad to π/2 rad, and the intensity of radio waves on the performance of a polycrystalline silicon solar cell under constant multispectral illumination. By solving the continuity equation in steady state, we derived the expression of the density of excess minority carriers, the photocurrent density, the photovoltage, the electric power and their dependence on the incidence angle and the intensity of the electromagnetic field is analyzed. Using the electric power curves versus junction dynamic velocity we determined the electric power lost at the junction, the maximum electric power and we calculated the conversion efficiency for various incidence angle and intensity of the electromagnetic field. The leakage photocurrent density, deduced from the photocurrent density curves versus junction dynamic velocity, and the electric power lost at the junction allowed us to calculate the shunt resistance of the solar cell according to the incidence angle and the intensity of the electromagnetic field. The numerical data show the negative effect of radios waves on the performance of a silicon solar cell.
