Bi₂I₆ is an inorganic semiconductor compound composed of bismuth and iodine, belonging to the family of metal halide semiconductors. This material is primarily of research interest for optoelectronic and photovoltaic applications, where its layered crystal structure and tunable bandgap make it a candidate for next-generation light-emitting devices, photodetectors, and potentially perovskite-alternative solar cells. While not yet commercially dominant, bismuth halides are investigated as lead-free and more environmentally stable alternatives to conventional halide perovskites in semiconductor device engineering.
