Original abstract
Abstract The need to develop ecologically friendly photovoltaic technologies has intensified research into lead-free perovskite photovoltaic cells. In this study, we simulated a planar solar cell design (FTO/ZnO/C60/MASnI3/CZTS/back contact) using the SCAPS-1D simulation package to determine the optimization techniques that can be employed to attain improved performance. The introduction of a ZnO/C60 bilayer as the electron transport region and a CZTS layer as the hole transport resulted in higher charge selectivity and lower interfacial losses. The thickness of the absorber, doping concentration, defect density, and interface trap density were systematically varied, and it was discovered that these parameters significantly influenced the performance of the device. Under the optimized conditions, the simulated device generated a power conversion efficiency of approximately 28.64 %, which indicates the importance of quality in the interfaces and defect prevention in the stable and efficient functioning of lead-free perovskite photovoltaic cells.
