General description
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).
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Find details here.
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.
