· Sn2BiS2I3

Sn₂BiS₂I₃ is a mixed-halide sulfide semiconductor compound combining tin, bismuth, sulfur, and iodine—belonging to the family of lead-free halide perovskites and related semiconductors being explored as alternatives to toxic lead-based materials. This is primarily a research-phase material investigated for photovoltaic and optoelectronic applications where non-toxic, earth-abundant absorber layers are needed; its layered structure and tunable bandgap make it a candidate for thin-film solar cells, photodetectors, and light-emitting devices, though practical device performance and stability remain active areas of development.

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.
