    Study and simulation of a tandem cell based on hydrogenated amorphous silicon and its alloys
    (université Ghardaia, 2024) GHOUL, Fatma Zohra
    In this study, we simulate three amorphous silicon photovoltaic cells, the first is in hydrogenated amorphous silicon a-Si:H, the second is in hydrogenated amorphous silicon germanium a-SiGe:H and the third is a tandem cell in a-Si:H and a-SiGe: H. This simulation was carried out using the program AFORS-Het (Automated FOR Simulation of heterojunction). In this study, we focused on the effect of the thickness and doping concentration of each layer on the characteristics of photovoltaic cells (open circuit voltage, short circuit current, form factor and efficiency)
