Cs2 Te1 I6

Cs₂TeI₆ is an inorganic halide perovskite ceramic composed of cesium, tellurium, and iodine. This is a research-stage material currently under investigation for optoelectronic and photovoltaic applications, rather than an established engineering ceramic. The perovskite halide family is of significant interest as a potential alternative to lead-based perovskites in next-generation solar cells, light-emitting devices, and radiation detectors, offering the possibility of non-toxic or lower-toxicity compositions while maintaining favorable light absorption and charge transport properties.
