· Cs2AgBiBr6

Cs2AgBiBr6 is a halide double perovskite semiconductor compound containing cesium, silver, bismuth, and bromine elements. It is primarily an experimental material under active research development, valued for its potential in optoelectronic and photovoltaic applications as a lead-free alternative to conventional perovskites. This material family is being investigated for next-generation solar cells, X-ray detectors, and light-emitting devices where reduced toxicity and improved stability compared to lead-based perovskites are critical design requirements.
