In₁.₃Cu₀.₇Se₂.₃ is a quaternary semiconductor compound combining indium, copper, and selenium in a layered chalcogenide structure. This material belongs to the family of copper-indium selenide semiconductors, which are primarily of research interest for photovoltaic and thermoelectric applications rather than established commercial production. The copper-indium-selenium system is valued for its tunable bandgap and potential in thin-film solar cells and next-generation energy conversion devices, though this particular stoichiometry represents an experimental composition rather than a widely standardized phase.
