What is Computational analysis of mixed cation mixed halide-based perovskite solar cell using SCAPS-1D software about?

Standard MAPbI3 (MAPI) perovskite suffers from stability and toxicity problems. In this numerical simulation study using SCAPS-1D software, we propose a hybrid perovskite (MA1−x FA x Pb1−y Sr y I3) to reduce these effects; thus, the influence of the mixture of formamidinium (NH2CHNH 2 + (FA+)), strontium (Sr), methylammonium (CH3NH 2 + (MA+)) and lead (Pb) on the electrical parameters of a hybrid perovskite-based solar cell is studied. This simulation was performed through modeling the perovskite absorber band gap depending on x and y proportions. This mixture leads to increase the crystallinity or stability by decreasing MA+ proportion by FA+, while the toxicity is reduced by decreasing Pb2+ proportion by Sr2+. We show that the substitution of 90% MA and 15% Pb (MA0.1FA0.9Pb0.85Sr0.15I3) to the standard MAPI radically changes the electrical parameters of the material and the performance of the solar cell. A maximum efficiency of 29% ( J s c = 24.2 mA/cm2, V o c = 1.37 V, F F = 87.49 %) is obtained in this simulation of the hybrid perovskite-based solar cell. These results are obtained after optimizing the hybrid perovskite band gap (Eg = 1.60 eV), layer thicknesses (0.400 μm for h
