Performance enhancement of (FAPbI3)1-x(MAPbBr3)x perovskite solar cell with an optimized design Bencherif, Hichem Meddour, Fayçal Hamdy Mohamed Elshorbagy, Mahmoud Hossain, M. Khalid Cuadrado Conde, Alexander Abdi, Mohamed Amir Kouda, Souhil Alda, Javier Bendib, Toufik In this paper, an optimized design of (FAPbI3)1-x(MAPbBr3)x perovskite solar cell is numerically investigated using SCAPS-1D software package. A variety of potential charge transport materials are investigated. Cu2O as HTL and ZnO as ETL outperform other choices; they are therefore considered as the best candidates. The impact of the electronic properties of both ZnO/perovskite and Perovskite/Cu2O interfaces on the solar cell performance is thoroughly investigated. We discovered that appropriate values of the conduction band offset (CBO+ = 0.29) and valence band offset (VBO+ = 0.09) assure a “spike-type” band alignment at both interfaces. This choice lowers the unwanted interfacial recombination mechanism, resulting in a challenging PCE. In addition, the impact of the work function of back contact is also investigated. According to simulation findings, Ni back electrodes with a work function of 5.04 eV is appropriate for Zn0.8Mg0.2O/(FAPbI3)0.85(MAPbB3)0.15/Cu2O perovskite solar cell. The optimized FTO/MgZnO/(FAPbI3)0.85(MAPbBr3)0.15/Cu2O/Ni PSC reaches a conversion efficiency as high as 25.86%. These findings will pave the way for the design of low-cost, high-efficiency solar cells. 2023-06-22T12:52:35Z 2023-06-22T12:52:35Z 2023-06-22T12:52:35Z 2022-09-28 journal article https://hdl.handle.net/20.500.14352/73281 2773-0131 (eISSN): 2773-0123 10.1016/j.micrna.2022.207403 eng DGRSDT restricted access Elsevier
