Abstract
Perovskite solar cells (PSC) have emerged as a prominent research area in solar cell development owing to their high‐efficiency and low‐cost photovoltaic technology. However, the transport layers typically employed in PSCs are organic materials, which may lead to unstable performance. In this work, a PSC with an indium tin oxide/WS2/FASnI3/Cd0.5Zn0.5S/Al configuration is proposed, and the parameters are optimized using the solar cell capacitance simulator‐1D program. In the present study, the impact of the WS2 layer thickness, electron‐transport layer material selection, absorber layer parameters, and interfacial defect states on the performance of the proposed solar cell is investigated. The optimized structure yields a power conversion efficiency of 23.1%, which is comparable to that of state‐of‐the‐art PSCs. The combination of an inorganic hole‐transport layer of WS2 presented in this work offers a novel approach to the development of PSCs.
