General description

This product aligns with one or more of the 12 Principles of Green Chemistry Find details here.
Copper selenide is an ionic conductor. 1 In nature, it occurs as mineral berzelianite. 2 Copper selenide may be prepared galvanically by coupled copper metal oxidation and Se reduction in alkaline selenosulfate (Na2SeSO3).

Application

Copper(I) selenide (Cu2Se) is a semiconductor material, which exists in cubic, tetragonal or orthorhombic forms. It forms thin films, which can be used as solar cell materials, optical filters, thermoelectric converters, electro-optical devices, and microwave shield coatings.
