· JVASP-36914· RbCaI3

RbCaI3 is a halide perovskite ceramic compound composed of rubidium, calcium, and iodine. This material belongs to the family of halide perovskites, which are primarily investigated for optoelectronic and photovoltaic applications rather than structural engineering use. As an experimental compound, RbCaI3 is of research interest for next-generation solar cells, radiation detectors, and light-emitting devices, where halide perovskites offer tunable bandgaps and solution-processability advantages over traditional semiconductors.
