· K1 Ag1 Br3

K1Ag1Br3 is a mixed-halide perovskite semiconductor compound containing potassium, silver, and bromine in a 1:1:3 stoichiometric ratio. This material belongs to the family of halide perovskites, which are actively investigated in photovoltaic and optoelectronic research for their tunable bandgap and light-absorption properties. As a silver-based variant, it represents an emerging alternative to lead halide perovskites, addressing toxicity concerns while exploring novel electronic and photonic behavior; however, this composition remains largely in the research phase rather than established industrial production.

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.
