Concluded that the use of the PSi treatment in PV cells leads to the increase in quantum efficiency and increases the efficiency of the solar cell compared to a cell without a PSi layer. We also investigated the addition of a BSF layer which also increases the yield.frPhotovoltaic solar cell; Porous silicon PSi; crystalline silicon c-Si; SCAPS-1D; internal quantum efficiency.Cellule solaire photovoltaïque ; Silicium Poreux; Silicium cristallin ; SCAPS-1D ; Rendement quantique interne.Thesis
