SnBr2 is a tin(II) bromide compound classified as an inorganic semiconductor material. It belongs to the family of halide perovskite precursors and tin-based semiconductors that are actively investigated for optoelectronic applications, particularly as an alternative to lead-based semiconductors due to lead's toxicity and environmental concerns. While primarily a research material rather than a mature commercial product, SnBr2 is notable for its potential in next-generation photovoltaic devices, thin-film transistors, and light-emitting applications where lead-free, tin-based semiconductors offer both environmental advantages and tunable electronic properties.
