Progress in Sb 2 Se 3 and Sb 2 S 3 ‐Based Solar Cells: SCAPS‐1D and Experimental Investigations

Abstract Antimony chalcogenides (Sb₂S₃ and Sb₂Se₃) have emerged as promising materials for solar energy conversion due to their exceptional optical and physicochemical properties. These materials are widely utilized as absorber layers in thin‐film solar cells, offering a cost‐effective and sustainable alternative for photovoltaic applications. In recent years, the solar cell capacitance simulator (SCAPS‐1D) has become an indispensable tool for predicting and optimizing solar cell performance, bridging the gap between theoretical modelling and experimental design. This article reviews the key insights from both experimental studies and SCAPS‐1D‐based simulations on Sb₂S₃ and Sb₂Se₃ solar cells. Despite significant progress, a notable disparity persists between theoretical predictions and experimental efficiencies, underscoring the need for further experimental advancements. This review also addresses current challenges and outlines future research directions to enhance the performance and scalability of Sb₂S₃ and Sb₂Se₃ solar cells. By offering a comprehensive overview, this work aims to benefit the researchers in advancing the development of high‐efficiency antimony chalcogenide‐based solar technologies.
