CsGeCl3 is a halide perovskite ceramic compound composed of cesium, germanium, and chlorine, representing a member of the lead-free perovskite family that has attracted significant research attention. This material is primarily investigated for optoelectronic and photovoltaic applications, where its direct bandgap and ionic conductivity properties make it a candidate for next-generation solar cells, light-emitting devices, and radiation detection systems. As a research-stage compound rather than a mature commercial material, CsGeCl3 is notable for avoiding the toxicity concerns associated with lead-based perovskites while maintaining semiconductor functionality, though stability and efficiency optimization remain active areas of development.
