Rb2CuBiBr6 is a lead-free halide perovskite compound containing rubidium, copper, and bismuth—an experimental material class currently under research for optoelectronic and photovoltaic applications. This composition represents an emerging effort to develop stable, non-toxic alternatives to lead-based perovskites, with potential relevance in next-generation solar cells, photodetectors, and solid-state light-emitting devices where toxicity constraints or regulatory pressure exclude conventional lead perovskites. The double-perovskite structure (A2B′B″X6) offers improved stability compared to single-cation perovskites, though material maturity remains in the laboratory phase.
