· Ce(InS2)3

Ce(InS2)₃ is a ternary semiconductor compound combining cerium with indium sulfide, belonging to the thiospinel or related sulfide semiconductor family. This material remains primarily in the research and development phase, investigated for potential optoelectronic and photovoltaic applications due to its tunable bandgap and mixed-valence metal composition. Interest in this compound stems from the broader exploration of rare-earth-containing semiconductors for next-generation solar cells, photodetectors, and solid-state lighting, where cerium doping or incorporation can modify electronic properties compared to binary indium sulfide systems.
