Cigs solar cell cigs properties cigs is a i iii vi compound semiconductor material composed of copper indium gallium and selenium.
Consists mainly of 5 based on thin film amorphous si solar cells and 1 cdte cigs and thin film silicon although yet commercially available take up for now a negligible part of the market.
A copper indium gallium selenide solar cell or cigs cell sometimes ci g s or cis cell is a thin film solar cell used to convert sunlight into electric power.
Advanced electrical simulation of thin film solar cells m.
Cigs is one of three mainstream thin film pv technologies the other two being cadmium telluride and amorphous silicon.
Because the material has a high absorption coefficient.
Ast s flexible cigs and novel packaging are highly adaptable to various applications thus power density and power to weight ratio can vary significantly with border width etc.

It is manufactured by depositing a thin layer of copper indium gallium and selenium on glass or plastic backing along with electrodes on the front and back to collect current.
Cigs has also been deployed in ultra high efficiency tandem cells with the potential to achieve 30 efficiency.
