· Pb4 I8

Pb₄I₈ is a lead iodide semiconductor compound that belongs to the perovskite and perovskite-related materials family. This is primarily a research and development material being investigated for optoelectronic and photovoltaic applications, particularly as an alternative or complementary material to methylammonium lead iodide in next-generation solar cells and light-emitting devices. The material is notable for its layered crystal structure, which can offer improved stability and tunable bandgap properties compared to conventional 3D perovskites, making it attractive for engineers exploring halide perovskite technologies with enhanced operational lifetimes.

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.
