KSn2I5
ceramic· JVASP-12539· KSn2I5
KSn2I5 is an inorganic ceramic compound in the halide perovskite family, combining potassium, tin, and iodine in a layered crystalline structure. This material is primarily investigated in research contexts for optoelectronic and photovoltaic applications, particularly as a lead-free alternative in next-generation solar cells and light-emitting devices where toxicity concerns limit lead-halide perovskites. Its notable advantage over conventional perovskites lies in the substitution of tin for lead, addressing environmental and regulatory constraints while maintaining potential for tunable bandgap and solution-based processing.

Regulatory Screening
Environmental
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.
