Investigation of the effect of different factors on the performance of several perovskite solar cells: a simulation study by SCAPS

Abstract

The new generation of solar cells based on perovskite materials has attracted  massive attention from the photovoltaic community, due to their high capability in supporting low-cost solar cell. In this study, extensive theoretical research of three types of lead-based  (MAPbI₃, FAPbI₃ and CsPbI₃) and four types of lead-free (MASnI₃, FASnI₃, CsGeI₃, and MAGeI₃) perovskite solar cells are modeled while Cu₂O is used as HTL and TiO₂ as ETL. The initial results show commendable performance for MAPbI₃ with 24,8% efficiency, while MAGeI₃ has the lowest performance (12,61%). In addition, different factors reviewed affect the performance almost similarly to the studied types of perovskites.
