CsCd4In5Se12

CsCd₄In₅Se₁₂ is a complex quaternary semiconductor compound composed of cesium, cadmium, indium, and selenium, belonging to the family of multinary chalcogenide semiconductors. This material is primarily of research interest for photovoltaic and photodetector applications, as the tuneable bandgap and layered crystal structure of chalcogenide systems make them candidates for next-generation solar cells and radiation detection. While not yet commercialized at scale, compounds in this chemical family are explored as alternatives to conventional cadmium telluride and lead-halide perovskites, offering potential advantages in stability and non-toxic element substitution, though synthesis complexity and performance optimization remain active research challenges.
