· CsSnI3

CsSnI₃ is a halide perovskite ceramic compound composed of cesium, tin, and iodine. This material is primarily studied in photovoltaic and optoelectronic research rather than deployed in established industrial applications; it belongs to the family of lead-free perovskites being developed as alternatives to conventional silicon and organic-inorganic hybrid solar cells. Engineers consider tin-based halide perovskites for next-generation solar technologies because they offer tunable bandgaps, solution processability, and reduced toxicity compared to lead-containing perovskites, though stability and reproducibility remain active research challenges.
