CIGS (Copper Indium Gallium Selenide) consists of Copper (Cu), Indium (In), Gallium (Ga) and Selenium. (Se). CIGS forms into phases under different temperatures and compositions. Chalcopyrite structure is the main CIGS application. Different compositions of elements lead to different semiconductor and light-absorbing properties. CIGS has a wide spectrum for light absorption. Its reliability and efficiency is the highest among different thin film technologies.
CIGS Module Structure
CIGS Module Functions
Solar modules are a device to convert sunlight into electricity.
CIGS modules function with the p-n interface consisting of P-type CIGS layer and N-type buffer layer. When sunlight is absorbed by the CIGS layer, electrons hit against each other and go through the buffer layer and hence electricity is generated. These are so called photoelectric effects. The direct currents generated by the modules can be converted into alternate currents so that solar systems can be integrated into the general power system.
