· JVASP-65769· Ba2SbBr

Ba2SbBr is an inorganic ceramic compound containing barium, antimony, and bromine elements, belonging to the halide perovskite family of materials. This is a research-stage compound being investigated primarily for optoelectronic and photovoltaic applications, where halide perovskites show promise as light-absorbing layers in next-generation solar cells and radiation detectors due to their tunable bandgaps and efficient charge transport properties. Engineers and materials scientists study Ba2SbBr and related halide perovskites as potential alternatives to lead-based perovskites, driven by the need for more stable, non-toxic, and environmentally benign semiconductor materials for energy conversion and sensing devices.
