The perovskite material with superior performance has made a huge impact on the photovoltaic application. However, the stability and the toxicity-related issues are still highly unaddressed. The optoelectronic properties of transition metals (TMs) and nontoxic nature of tin (Sn) halide perovskite (MASnX3) could be anticipated to overcome both the stability and toxicity concerns. This article encompasses numerical simulation and analysis of Sn-based perovskite solar cell device structure with TM compounds such as molybdenum oxide (MoOx), molybdenum ditelluride (MoTe2), and tungsten diselenide (WSe2) as a hole transport material (HTM). The device parameters were optimized and simulated using batch calculations and the efficiencies were found to be 25.19%, 23.32%, and 24.33%, for MoOx, WSe2,and MoTe2, respectively, which is very high. The device with MoOx as HTM have shown prominent results compared with other with a short circuit current density (Jsc) 0.6 mA/cm2, open-circuit voltage (Voc) of 0.023 eV, fill factor of 0.21% and an increase of 1.09% in power conversion efficiency. These results suggest that these TMs can be a highly competent material for solar cell device structures.
