Antimony selenosulfide (Sb₂(S,Se)₃) thin film solar cells have become a research hot spot in recent years due to their simple preparation method, abundant raw materials, low toxicity, stable performance, etc. Their power conversion efficiencies have exceeded 10%, showing the potential for industrialization. The research focus on Sb₂(S,Se)₃ solar cells is to improve the quality of the absorption layer and optimize the device structure. Firstly, the mainstream growth process of Sb₂(S,Se)₃ thin film is systematically introduced. Secondly, the selection of each functional layer and the gradient bandgap structure of Sb₂(S,Se)₃ solar cells are analyzed. Finally, the large-scale preparation of Sb₂(S,Se)₃ solar cells and their application potential in antimony-based multi-junction solar cells are further prospected to provide a feasible reference for promoting the industrialization of Sb₂(S,Se)₃ solar cells.
