CsGeI3

CsGeI3 is a halide perovskite semiconductor compound composed of cesium, germanium, and iodine, representing an emerging class of lead-free inorganic perovskites. This material is primarily investigated in research settings for optoelectronic applications where toxicity concerns and stability advantages over lead-based perovskites are critical; it shows promise in photovoltaics, X-ray detection, and light-emitting devices, though it remains largely experimental compared to more mature semiconductor technologies.
