K2CuBiI6
metal· JVASP-106422· K2CuBiI6
K2CuBiI6 is a halide perovskite compound containing potassium, copper, bismuth, and iodine—a member of the emerging double-perovskite family being investigated for optoelectronic and photovoltaic applications. This is primarily a research-phase material rather than an established industrial compound; it is being studied for its potential in next-generation solar cells, light-emitting devices, and radiation detection due to its tunable bandgap and stability advantages over lead-based perovskites. The bismuth-copper framework offers promise as a less-toxic alternative to conventional perovskites while maintaining semiconducting properties relevant to energy conversion.
