Research progress on tunable band gap antimony sulfoselenide thin films and solar cells

Antimony selenosulfide(Sb (2)(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 Sb (2)(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 Sb (2) ( S,Se) (3) thin film is systematically introduced. Secondly,the selection of each functional layer and the gradient bandgap structure of Sb (2) ( S,Se) (3) solar cells are analyzed. Finally,the large-scale preparation of Sb (2) ( 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 Sb (2) ( S,Se) (3) solar cells.
