Numerical analysis and performance improvements of nanostructured Cu2O / CH3NH3PbI3 / ZnSe in heterojunction solar cells have been documented in this paper. The choice for conventional solar cells reaching maximum efficiency of 22.1 percent is predominant for Perovskite photovoltaics. In recent years, organic-inorganic hybrid perovskite solar cells in the photovoltaic research community have gained great interest because of their ease of processing. Low manufacturing costs, excellent characteristics of light-harvesting, A relatively high performance Making it more appealing than other current materials from solar cells. In this study, a numerical simulation using the Solar Cell Capacitance Simulator (SCAPS) of a thin film heterojunction perovskite solar cell to study some parameters that can affect the performance of CH3NH3PbI3 PSC with Cu2O as HTL and ZnSe as ETL performed. The absorber material thickness, ETL and HTL, the absorber material bandgap, and ETL were investigated. Results have shown that the thickness of ZnSe greatly influences the device’s P Process / Analysis: The Capacitance Simulator(SCAPS) is used to perform the study of solar cell design. It is a computer-based software tool and is well adapted for homo and heterojoint, multi-junction, and photovoltaic structure analysis. This software instrument is based on the continuity and Poisson equation of the Holes and Electrons. It is used to optimize the different parameters, such as thickness and temperatures, for this model. CE. As the thickness of ZnSe decreases, the efficiency of the cell increases.
