Inorganic Lead-Free B-γ-CsSnI₃ Perovskite Solar Cells Using Diverse Electron-Transporting Materials: A Simulation Study.

ABSTRACT: B-γ-CsSnI₃ perovskite solar cells (PSCs) are simulated employing diverse electron-transporting layers (ETLs, including TiO₂, ZnO, SnO₂, GaN, C₆₀, and PCBM), and a comparative study has been made. Both regular and inverted planar structures are simulated. Effects of the thickness of absorbers and ETLs, doping of ETLs, and interface trap states on the photovoltaic performance are studied to optimize the device structures. The regular structures have larger short-circuit current density (J _sc) than the inverted structures, but the inverted structures have larger fill factor (FF). All of the simulated optimal PSCs have similar open-circuit voltages (V _oc) of ∼0.96 V. The PSCs with TiO₂ ETLs have the best
