ABSTRACT: In this research, we investigated the potential of the hybrid organic-inorganic material (CH3NH3)2CuCl4 as an absorber in perovskite solar cells (PSCs). Perovskite solar cells are becoming more popular as a potential boost to the efficiency of traditional photovoltaic cells. The advantages of this cell over commercial silicon or other organic and inorganic solar cells are its high efficiency and eco-friendliness. In this study, we used the SCAPS-1D software to improve device performance parameters, employing ZnSe as the electron transport layer and SrCu2O2, a promising hole-transport material identified in (CH3NH3)2CuCl4 -based perovskite solar cells (PSCs). To further enhance device performance, we have analyzed the effects of absorber and buffer layer thickness, acceptor density, absorber defect density, and interfacial defect densities at the ETL/Absorber and Absorber/HTL interfaces. In addition, we analyzed the effects of operating temperature, series resistance, and shunt resistance on the quantum efficiency, back contact materials, current density-voltage, and overall optimum device performance. Gold is utilized for the back contact. The efficient perovskite solar cell achieved an exceptionally high efficiency of 28.5% with a 0.05 μm buffer layer and a 0.6 μm absorber layer. The proposed solar cell structure may enable high-performance perovskite solar cells.
