· K1.83Cd1.83Bi2.17S6

K1.83Cd1.83Bi2.17S6 is a mixed-metal sulfide semiconductor compound combining potassium, cadmium, and bismuth in a layered crystal structure. This is a research-phase material investigated primarily for optoelectronic and photovoltaic applications due to its tunable bandgap and potential for wide-spectrum light absorption; it belongs to the family of heavy-metal chalcogenides being explored as alternatives to lead-based perovskites for next-generation solar cells and photodetectors. While not yet commercialized, materials in this class are of interest because they offer potential toxicity advantages over lead-containing semiconductors and may enable efficient light harvesting across broader wavelength ranges than conventional silicon or conventional III–V compounds.

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.
