Cadmium indium diselenide (Cd(InSe₂)₂) is a ternary semiconductor ceramic compound belonging to the chalcogenide family, combining cadmium, indium, and selenium elements. This material is primarily investigated in research and emerging photovoltaic applications, particularly for thin-film solar cells and photodetectors where its direct bandgap and tunable optoelectronic properties offer advantages over single-binary semiconductors. While not yet widely commercialized, the ternary chalcogenide family shows promise for next-generation solar technologies requiring improved light absorption and carrier transport compared to conventional silicon or CdTe devices.
