· Rb1 Cu1 Br3

RbCuBr₃ is a halide perovskite semiconductor compound composed of rubidium, copper, and bromine. This material belongs to the emerging class of metal halide perovskites, which are primarily of research and developmental interest rather than established industrial production. The compound is investigated for potential applications in optoelectronic devices, photovoltaics, and light-emitting systems, where its tunable bandgap and crystalline structure offer advantages in absorbing and emitting light, though engineering adoption remains limited pending stability and scalability improvements.
