ceramic

· JVASP-36883· RbSnBr3

RbSnBr3 is a lead-free halide perovskite ceramic compound, part of the ABX3 perovskite family where rubidium serves as the A-site cation, tin as the B-site metal, and bromine as the halide. This material is primarily investigated in research and development contexts for optoelectronic and photovoltaic applications, where it offers potential as a non-toxic alternative to lead-based perovskites. The rubidium-tin-bromine composition is notable for balancing structural stability with reduced environmental and health concerns compared to conventional lead halide perovskites, making it relevant for next-generation solar cells, light-emitting devices, and radiation detection systems.
