Opis:: The aim of this work is to investigate a theoretical study of a vertical junction silicon solar cell capacitance under monochromatic illumination. By solving the continuity equation and using a one dimensional model in frequency modulation, we derive the analytical expressions of both excess minority carrier density and photovoltage. Based on these expressions, the solar cell capacitance was calculated; we then exhibited the effects of both temperature and incidence angle on the solar cell capacitance.

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:: 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.

Opis:: Praca przedstawia projekt instalacji fotowoltaicznej, w skład której wchodzą technologie barwnikowych ogniw organicznych DSSC oraz krzemowe, wysokowydajne ogniwa typu back-contact. Oba rozwiązania opisano i scharakteryzowano ich zalety oraz wady. Projekt swym zasięgiem obejmuje południowo-wschodnią część budynku „K” Politechniki Rzeszowskiej W pracy przedstawiono również krótką charakterystykę warunków solarnych Rzeszowa na podstawie danych meteorologicznych ze stacji Rzeszów-Jasionka. Korzystając z oprogramowania PVSOL przeprowadzono symulację systemu pod kątem potencjalnych zysków energii, które porównano z aktualnymi potrzebami energetycznymi budynku.
The paper presents the design of photovoltaic installation, which covers the south-eastern part of the building "K" of Rzeszów University of Technology. In this building there are rooms of the Department of Physics, being the initiator of the project. This work describes the Polish solar conditions, in particular Subcarpathian (Fig. 1) [3, 4, 11]. In the following characterizes key assumptions the design. There is described the principle of operation of photovoltaic technologies used with the advantages and disadvantages of each of them [15]. The basic parameters of the cells used in the project, together with the Energy Management System are characterized [13]. The paper presents design solutions fixing installations and drawings showing the appearance of the facade covered by installing a PV system (Figs. 4-9). Using the software PVSOL Valentin, the authors performed a simulation of the designed system for potential energy yields and estimated the theoretical efficiency of the installation for the parameters assumed in the project. The results are presented in the form of graphs and compared with the current energy needs of the building (Figs.10-11). Based on the obtained results, it was found that the designed system would only cover about 10% of the building electricity.
