· JVASP-69329· Ba2BiBr

Ba2BiBr is an inorganic ceramic compound composed of barium, bismuth, and bromine, belonging to the halide perovskite family of materials. This is a research-stage compound under investigation for optoelectronic and photovoltaic applications, where bismuth-based halide perovskites are being explored as lead-free alternatives to conventional lead halide perovskites due to their potential for reduced toxicity. The material's notable advantage lies in its environmental and health profile compared to lead-based semiconductors, making it relevant for next-generation solar cells, photodetectors, and light-emitting devices, though it is not yet established in high-volume commercial production.
