CsInI3

CsInI₃ is a halide perovskite ceramic compound composed of cesium, indium, and iodine—a member of the inorganic perovskite family with a cubic crystal structure. This is a research-stage material primarily investigated for optoelectronic and photovoltaic applications due to its direct bandgap and potential for efficient light absorption and emission, though it remains less developed than lead-based or hybrid organic-inorganic perovskites. Engineers and researchers evaluate it as a lead-free alternative for next-generation solar cells, X-ray detectors, and scintillators, where its compositional stability and lower toxicity offer advantages over conventional perovskites, though processing challenges and efficiency improvements remain active areas of study.
