Numerical Design and Performance Optimization of Lead‐Free CsSnGeI3 Perovskite Solar Cells Using Cu2O Hole Transport Layer via SCAPS‐1D

Energy Science &Engineering, EarlyView.
The optimal structure of the device FTO/ZnS/CsSnGeI3/Cu2O/Au consists of a CsSnGeI3 absorber layer and ZnS as the buffer layer, FTO as the electron transport layer, and Cu2O as the hole transport layer. For the back contact, gold is utilized. According to the current density–voltage curve, efficiency increases with thickness concurrently.
