Abstract

Abstract: The use of multilayer p-graphene as hole transporting layer has been successfully shown to improve the performance of perovskite solar cell. The structure of p-graphene/CH3 NH3 PbI3 /n-cSi is designed and simulated in AFORS-HET software. We optimized the parameters of single layer p-graphene and obtained power conversion efficiency (PCE) of 12.21% under an illumination of AM 1.5G. With an increase in the number of p-graphene layers, the PCE falls down to 10.01%. The optimization of active layer parameters increases the PCE up to 12.27%. Further optimization of n-cSi parameters lead to the highest PCE of 16.75%. A significant effect of the operating temperature on the solar cell performance is observed. The effect of textured front surface on the solar cell performance is also studied and a PCE of 17.90% is obtained for textured surface as compared to 16.75% for planar surface. Our studies indicated that p-graphene may act as an efficient hole transporting layer in perovskite solar cell. Highlights: Proposed perovskite solar cell structure is simulated using AFORS-HET software. p-graphene and n-cSi serve as an effective HTL and ETL respectively. The performance of the solar cell significantly depends on the material properties. Increase in temperature decreases the efficiency of the solar cell. The structure with textured surface shows enhanced performance up to 17.90%.
