Cigs solar cell cigs properties cigs is a i iii vi compound semiconductor material composed of copper indium gallium and selenium.
Th in 0 33mm lightweight 7 5 gm ideal for many specialized uses.
Like these materials cigs layers are.
The material is a solid solution of copper indium selenide often abbreviated cis and copper gallium selenide with a chemical formula of cuinxga 1 x se2 where the value of x can vary from.
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.
Range noted 2is specific to fully laminated modules presently available with areal density ranging from 310 400 g m.
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.
Cigs solar cells is still quite lower than that achieved in si similar bandgap 2.
Most enterprises favour the crystalline technology because of former problems.
Because the material has a high absorption coefficient.
The window materials tcos and cds are responsible for the.
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.
