CsMgI3

CsMgI₃ is a halide perovskite ceramic compound composed of cesium, magnesium, and iodine. This is primarily a research material under investigation for optoelectronic and photovoltaic applications, particularly as a lead-free alternative in next-generation perovskite solar cells and light-emitting devices. It is notable for its potential to address toxicity concerns associated with lead-based perovskites while maintaining favorable bandgap and electronic properties for energy conversion and solid-state lighting.
