Bismuth iodide (BiI₂) is an inorganic ceramic compound composed of bismuth and iodine, belonging to the halide perovskite family. It is primarily of research interest for optoelectronic and photovoltaic applications, particularly in emerging thin-film solar cells and radiation detection devices where its semiconducting properties and relative stability make it a candidate alternative to lead-based halide perovskites. While not yet commercially dominant, BiI₂ is investigated for its potential in next-generation photovoltaic materials and sensing technologies, where reduced toxicity compared to lead compounds and tunable electronic properties offer advantages for specialized engineering applications.
