· JVASP-136809· PbI

Lead iodide (PbI) is an inorganic ceramic compound that exists primarily as a research material in the perovskite family, though it is more commonly encountered as PbI₂ in practical applications. It is studied intensively for optoelectronic and photovoltaic applications, particularly as a precursor material and component in hybrid perovskite solar cells, where its semiconducting and radiation-detection properties are leveraged. Engineers and researchers select lead iodide compounds for their tunable bandgap, strong light absorption, and potential in next-generation energy conversion devices, though commercial deployment remains limited due to stability and toxicity considerations that drive ongoing research into alternative formulations.

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.
