Cs3Sb2Br9

Cs3Sb2Br9 is a halide perovskite semiconductor compound composed of cesium, antimony, and bromine, belonging to the emerging class of lead-free perovskite materials. This is primarily a research-stage material currently under investigation for photovoltaic and optoelectronic applications, as it addresses toxicity concerns associated with traditional lead-based perovskites while maintaining semiconductor functionality. The material is notable for its potential use in next-generation solar cells, light-emitting devices, and radiation detection systems where reduced environmental and health risks are critical design requirements.
