Cuprous Selenide Market – View in Detailed Research Report

Cuprous Selenide (Cu2Se) is an inorganic chemical compound appearing as a black cubic crystal with a high relative density of 6.749 and a melting point of 1113°C. It is primarily synthesized by heating a stoichiometric mixture of copper and selenium in a vacuum‑sealed quartz tube or through chemical reduction methods. This semiconductor material is critically important in advanced technological applications, most notably in the manufacturing of copper indium gallium selenide (CIGS) thin‑film solar cells, which are prized for their high efficiency and flexibility. Furthermore, it is utilized in thermoelectric converters, optical filters, and as a sputtering target for various coatings.
