BiI3
semiconductor· BiI3
Bismuth iodide (BiI₃) is a layered halide perovskite semiconductor with a narrow bandgap, belonging to the family of metal halides under investigation as alternatives to lead-based perovskites in photovoltaic and optoelectronic devices. The material is primarily of research interest rather than commercial production, valued for its lower toxicity compared to lead halides while maintaining semiconducting properties suitable for light absorption and charge transport. Its layered crystal structure and moderate mechanical properties make it a candidate for flexible and thin-film optoelectronic applications, though performance optimization and stability remain active areas of development.

Export Control
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.
