Utilizing ABX 3 -based perovskites for solar cell applications has proven to be a sustainable choice, offering a suitable substitution for non-renewable energy sources. However, employing these types of solar cells is challenging due to the thousands of possible perovskite solar cells that can be formed. The present study focused on selecting a suitable perovskite solar cell structure among commonly considered organic-inorganic solar cell structures. This was achieved by classifying performance data from poor to good and screening the good data for further investigation. Following this selection, the optimization process was initiated to improve cell performance. This process was accomplished in several phases, including optimization of perovskite solar cell layer properties and working points. The results of perovskite layer optimization indicated that, with respect to recombination issues, choosing a cell with relatively high absorber thicknesses and low perovskite layer doping densities yields better performance. For working point optimization, simulation results suggested lower temperatures and series resistances, and higher shunt resistances. Results revealed that the CuSCN/TiO₂/FASnI₃ structure achieved the highest power conversion efficiency of 26.03%, with a short-circuit current density of 27.75 mA·cm⁻², an open-circuit voltage of 1.13 V, and a fill factor of 83.16%. The optimization process employed in this study led to a 1% efficiency improvement, raising the efficiency to 26% based on an optimized structure.
