· Sr2 Bi2 I2 O4

Sr₂Bi₂I₂O₄ is a mixed-halide perovskite-related semiconductor compound combining strontium, bismuth, iodine, and oxygen in a layered structure. This is an experimental material currently under research investigation for next-generation photovoltaic and optoelectronic applications, particularly as a lead-free and tin-free alternative to conventional perovskites. The compound is notable for its potential to combine the light-absorption and charge-transport capabilities of perovskites with improved environmental stability and reduced toxicity compared to lead or tin-based systems, though commercial deployment remains at the research stage.
