Cs₂TeI₆ is a halide perovskite semiconductor composed of cesium, tellurium, and iodine. This compound belongs to the emerging class of inorganic perovskites and is primarily investigated as a material for optoelectronic devices, particularly photovoltaic and light-emission applications. Unlike organic-inorganic hybrid perovskites, its all-inorganic composition offers improved thermal and chemical stability, making it attractive for research into next-generation solar cells, X-ray detectors, and scintillation devices where long-term durability is critical.
