· JVASP-99697· K2CuSbI6

K2CuSbI6 is a halide perovskite compound containing copper and antimony, representing an emerging class of materials in the inorganic perovskite family. This is primarily a research-phase material studied for optoelectronic and photovoltaic applications due to its tunable electronic structure and potential for stable, non-toxic alternatives to lead-based perovskites. The material's notable advantage over conventional halide perovskites is the substitution of toxic lead with antimony and copper, offering improved environmental and health compatibility while maintaining semiconducting properties relevant to energy conversion and light-emission technologies.
