Abstract: High Resolution Image Download MS PowerPoint Slide This paper reports the simulation and optimization of heterojunction perovskite solar cells (PSCs) with a proposed structure of TiO 2 /i-CH 3 NH 3 SnBr 3 /CsPbI 3 /Al(BSF) using SCAPS-1D software. The purpose of this study is to investigate the performance of the PSC with CsPbI 3 perovskite active layers and i-CH 3 NH 3 SnBr 3 as the permeable layer. Therefore, the thicknesses of the layers of the heterojunction perovskite are modified in order to find a better conversion efficiency of the solar cell, where the latter’s performance is improved by optimizing the absorber’s thickness, which is found to be 1 μm, with a permeable layer of 15 μm. The device efficiency of the i-CH 3 NH 3 SnBr 3 /CsPbI 3 heterojunction is improved to 38.98%, and optimized parameters are V oc = 1.21 mV, J sc = 35.63 mA/cm 2, and FF = 89.84%. The acceptor concentration ( N a ), donor concentration ( N d ), defect density, and series and shunt resistances are also investigated.
