· JVASP-56905· RbSn2Br5

RbSn2Br5 is a mixed-halide perovskite ceramic compound combining rubidium, tin, and bromine elements. This material belongs to the halide perovskite family, primarily of research interest for optoelectronic and photovoltaic applications rather than established industrial production. The tin-based composition offers potential advantages in stability and toxicity profiles compared to lead halide perovskites, making it a candidate for next-generation solar cells, light-emitting devices, and radiation detection systems, though commercialization remains limited and material processing requires specialized techniques.
