· Cu2 B2 Se4

Cu₂B₂Se₄ is a quaternary semiconductor compound composed of copper, boron, and selenium, belonging to the class of metal chalcogenides with potential for photovoltaic and optoelectronic applications. This material is primarily of research interest rather than established commercial production, studied for its semiconducting properties and potential use in thin-film solar cells, photodetectors, and other quantum electronic devices where its band gap and crystal structure may offer advantages over conventional semiconductors. The copper-boron-selenide family is notable for combining relatively abundant elements and tunable electronic properties, positioning it as a candidate for cost-effective alternatives to traditional III-V semiconductors, though significant development work remains before widespread industrial adoption.
