PbI2
semiconductorLead iodide (PbI₂) is a layered semiconducting compound that belongs to the halide perovskite family, characterized by a hexagonal crystal structure and van der Waals-bonded layers. While primarily investigated as a research material for next-generation optoelectronic devices, PbI₂ is industrially significant as a precursor material in the synthesis of hybrid organic-inorganic perovskites (such as methylammonium lead iodide) used in high-efficiency photovoltaic cells and light-emitting applications. Engineers select PbI₂ for its tunable bandgap, strong light-absorption characteristics, and solution-processability, making it attractive for low-cost, scalable thin-film device manufacturing where conventional silicon or III-V semiconductors are cost-prohibitive.
