Abstract :Perovskite solar cells have gained significant attention due to their excellent photovoltaic performance and simple manufacturing process. However, the use of lead insert ignore into journalissuearticles values(Pb); in the widely studied CH3NH3PbI3 perovskite material limits its large-scale production due to low stability in the air. As a result, researchers have turned to lead-free CH 3 NH 3 SnI 3 perovskite as a promising alternative. In this study, we used one-dimensional simulation software to investigate the photovoltaic properties of CH 3 NH 3 SnI 3 perovskite solar cells with a TiO 2 /CH 3 NH 3 SnI 3 /Cu 2 O structure. By adjusting the thickness of the absorbing layer, doping concentration, and density of defects, we were able to improve the performance of the solar cells. The obtained results of Jsc= 31,519 mA/cm 2 , Voc = 0,965V, FF = 78,717%, and PCE = 23,943% demonstrate the potential of lead-free CH 3 NH 3 SnI 3 as a highly efficient and environmentally friendly solar absorber.
