· Cs3Sn3Cl7F2

Cs3Sn3Cl7F2 is a halide perovskite semiconductor compound combining cesium, tin, chlorine, and fluorine elements in a layered crystal structure. This material belongs to the emerging class of tin-based halide perovskites, which are being investigated as lead-free alternatives for optoelectronic and photovoltaic applications due to their reduced toxicity compared to conventional lead halide perovskites. The mixed halide composition (chlorine and fluorine) offers tunable bandgap and improved phase stability, making it relevant for research into next-generation solar cells, light-emitting devices, and radiation detection systems where both performance and environmental/health safety are critical design constraints.

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.
