Copper indium gallium selenide solar cell

CIGS is a I-III-VI 2 compound semiconductor material composed of copper, indium, gallium, and selenium.The material is a solid solution of copper indium selenide (often abbreviated "CIS") and copper gallium selenide, with a chemical formula of CuIn x Ga (1−x) Se 2, where the value of x can vary from 1 (pure copper indium selenide) to 0 (pure copper gallium selenide).

How a Solar Cell Works

A solar cell is made of two types of semiconductors, called p-type and n-type silicon. The p-type silicon is produced by adding atoms—such as boron or gallium—that have one less electron in their outer energy level than does silicon. Because boron has one less electron than is required to form the bonds with the surrounding silicon atoms, an electron vacancy or "hole" is created.
