KSnI3-based perovskite solar cells have attracted a lot of research interest due their unique electronic, optical, and thermal properties. In this study, we optimized the performance various lead-free cell structures-specifically, FTO/Al-ZnO/KSnI3/rGO/Se, FTO/LiTiO2/KSnI3/rGO/Se, FTO/ZnO/KSnI3/rGO/Se, FTO/SnO2/KSnI3/rGO/Se, using SCAPS-1D simulation tool. The optimization focused on thicknesses dopant densities rGO, KSnI3, Al-ZnO, LiTiO2, ZnO, SnO2 layers, thickness FTO electrode, as well defect density KSnI3. This yielded PCE values 27.60%, 24.94%, 27.62%, 30.21% for FTO/SnO2/KSnI3/rGO/Se configurations, respectively. device is 7.43% more efficient than FTO/SnO2/3C-SiC/KSnI3/NiO/C device, which currently highest performing in literature. Thus, our structure now, by far, most PSC design. Its best achieved under ideal conditions series resistance 0.5 Ω cm2, shunt 107 temperature 371 K.
