· SnI4

SnI₄ (tin iodide) is an inorganic semiconductor compound composed of tin and iodine, belonging to the halide perovskite and post-perovskite material families. This material is primarily investigated in research contexts for optoelectronic and photovoltaic applications, where its bandgap and charge-transport properties show promise as an alternative to lead-based perovskites. Engineers and researchers are exploring SnI₄ because tin-based halides offer reduced toxicity compared to conventional lead halide semiconductors while maintaining suitable electronic properties, though commercial-scale adoption remains limited and material stability remains an active research challenge.
