Cigs is one of three mainstream thin film pv technologies the other two being cadmium telluride and amorphous silicon.
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.
Cigs solar cell miasolé thin film cigs solar cells on stainless steel substrate have high efficiency levels and provide significant advantages over conventional rigid solar cells.
Like these materials cigs layers are.

Most enterprises favour the crystalline technology because of former problems.
Cigs has also been deployed in ultra high efficiency tandem cells with the potential to achieve 30 efficiency.
Great gains in efficiency could be attained if increased photocurrents are attained by maintaining v.
As of 2018 cigs cell efficiencies have surpassed all other thin film pv technologies achieving 2.

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.
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.
