Cu0.01In1.99Se2.99 is a copper-doped indium selenide compound semiconductor with a nominal composition approaching InSe with minimal copper substitution. This material belongs to the III–VI semiconductor family and is primarily of research interest for photovoltaic and optoelectronic applications, where the copper doping is investigated to modify electronic properties and carrier dynamics compared to undoped InSe. The composition falls within the thin-film solar cell and photodetector development space, where InSe-based semiconductors are explored as alternatives to more mature CdTe or CIGS systems due to their tunable bandgap and potential for high absorption coefficients.
