· 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.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
