Recently, organo-metal halide perovskite solar cells based on planar architecture have demonstrated an exceptional progress These structures show lower defect density, high carrier mobility, and broader absorption spectra in compare to other solar cells. In this work a 3D finite element method (FEM) technique is used to simulate a planer perovskite solar cell. Coupled electrical-optical modeling is constructed to fully characterize the proposed device. We investigate variation of short circuit current (J_sc), open circuit voltage (V_oc) and fill factor (FF) in different temperature ranges (280-340 K). Also, the effect of material replacement (Cu₂O material instead of CuSCN), as hole transport material (HTM), has been investigated on solar cell performance. It is caused to change Jsc. Based on the result the best PCE is 14.32%. These simulation results open up a way to find accurate design parameters in solar cell with best performance.
