· In3CuSe5

In₃CuSe₅ is a ternary semiconductor compound composed of indium, copper, and selenium, belonging to the chalcopyrite-related family of materials used in photovoltaic and optoelectronic devices. This material is primarily of research and development interest for thin-film solar cells and infrared detectors, where its direct bandgap and photosensitivity offer potential advantages over traditional silicon-based semiconductors in specialized wavelength applications. Engineers consider In₃CuSe₅ as an alternative absorber layer material in next-generation photovoltaic architectures, though it remains less commercially established than related compounds like CIGS (copper indium gallium diselenide), making it most relevant for emerging technologies and laboratory-scale device development.
