In this paper, the influence of absorber defect density and acceptor doping concentration variation is analyzed in terms of J-V, QE-λ, bandgap alignment, and recombination rate to compare the performance of methylammonium lead halide (MAPbI3) and formamidinium lead halide (FAPbI3) solar cells. For this, two conventional planar type architectures viz. Glass/ZnO/MAPbI3/Spiro-OMeTAD/Au and Glass/ZnO/FAPbI3/Spiro-OMeTAD/Au were simulated and compared using SCAPS-1D. The analysis of simulation results revealed that the FAPbI3 cell showed better performance with maximum power conversion efficiency of 21.26%, open-circuit voltage of 0.9989 V, short circuit current of 26.75 mA/cm2, and fill factor of 79.80%. While, MAPbI3 cells showed maximum power conversion efficiency of 18.17%, open-circuit voltage 0.9784 V, short circuit current of 23.75 mA/cm2, and fill factor of 78.17%. This comparison provides information about the best alternative thin-film, perovskite solar cell (PSC) having high efficiency.
