Flexible copper indium gallium selenide thin film photovoltaic panel

CIGS is one of three mainstream thin-film photovoltaic (PV) technologies, the other two being cadmium telluride and amorphous silicon. Like these materials, CIGS layers are thin enough to be flexible, allowing them to be deposited on flexible substrates.OverviewA copper indium gallium selenide solar cell (CIGS cell, sometimes CI(G)S or CIS cell) is a used to convert sunlight into electric power. It is manufactured by depositing a thin layer of . CIGS is a --2 compound composed of,,, and . The material is a of copper indium selenide (often abbreviated "CIS") and copper gallium selenide, w. . The most common device structure for CIGS solar cells is shown in the diagram (see Figure 1: Structure of a CIGS device). of about of 1–3 thickness is commonly used as a substrate, because the.
