Performance Analysis of MoS2/MASnI3/WSe2 Based Solar Cell with More Than 31% Efficiency

In recent years, there have been advancements in the performance of Perovskite solar cells, which have opened avenues for their commercialization. Lead-based perovskites have reached efficiencies surpassing 25% in single junction setups. However, the issue of lead toxicity has prompted a shift in focus towards organic-inorganic halide materials within the solar cell industry. This paper examines the performance of MASnI3-based PSC, emphasizing the critical role of numerical analysis in their design. Here SACPS-1d, a solar cell simulator is used to model an optimized MASnI3 solar cell that incorporates a 2D WSe2 hole transport layer (HTL) and a 2D MoS2 electron transport layer (ETL). The combination of WSe2 and MoS2 with the MASnI3 absorber layer achieves a remarkable power conversion efficiency (PCE) of 31.77%, with a peak current density (Jsc) of 32.952212 mA/cm<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> and a voltage output (Voc) of 1.1173 V. This research enhances the understanding of single-junction PSC.
