chemical spray pyrolysis
heterojunction solar cell
n-ZnO/p-Si - 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.
