· SnI2

Tin iodide (SnI₂) is an inorganic semiconductor compound belonging to the halide perovskite family, characterized by tin cations bonded with iodide anions in a layered crystal structure. While primarily explored in research rather than mature industrial production, SnI₂ is investigated for optoelectronic and photovoltaic applications due to its tunable bandgap and potential for lead-free alternatives in next-generation solar cells and light-emitting devices. Engineers consider it for emerging technologies where toxicity concerns and material stability drive the search for tin-based semiconductors over traditional lead halide perovskites.
