· Ag2 Bi2 I8

Ag₂Bi₂I₈ is a mixed-halide semiconductor compound combining silver, bismuth, and iodine in a layered perovskite-like structure. This material is primarily of research interest for next-generation optoelectronic and photovoltaic applications, where it is being investigated as an alternative to lead-halide perovskites for solar cells and light-emitting devices due to its potential lower toxicity and improved stability. The compound represents an emerging class of double-perovskite semiconductors that aim to balance performance with environmental and health concerns raised by conventional lead-based candidates.
