· Pb5 S2 I6

Pb₅S₂I₆ is a mixed-halide perovskite semiconductor composed of lead, sulfur, and iodine. This is primarily a research compound rather than an established commercial material, investigated for optoelectronic and photovoltaic applications where tunable bandgap and solution-processability are desired. The material belongs to the broader family of halide perovskites being explored as an alternative to conventional silicon in next-generation solar cells, light emitters, and radiation detectors, with potential advantages in cost and manufacturing flexibility compared to traditional semiconductors.

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.
