· JVASP-12543· KSn2Br5

KSn2Br5 is a halide perovskite ceramic compound composed of potassium, tin, and bromine—a member of the lead-free perovskite family that has emerged as a research focus for optoelectronic and photovoltaic applications. This material is primarily investigated in laboratory and developmental contexts rather than established industrial production, valued for its potential in perovskite solar cells, light-emitting devices, and radiation detection where lead-free alternatives are required due to environmental and regulatory constraints. Engineers consider tin-based halide perovskites like KSn2Br5 when designing next-generation energy conversion or sensing devices that demand both performance and reduced toxicity compared to traditional lead perovskites.

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.
