Copper Indium Gallium Selenide Cigs Thin Film Photovoltaic Solar Panels

Because the material has a high absorption coefficient and strongly absorbs sunlight a much thinner film is required than of other semiconductor materials.

Copper indium gallium selenide cigs thin film photovoltaic solar panels. Copper indium gallium selenide cigs solar cell is a thin film solar cell which is used for converting sunlight into electricity. Cigs is one of three mainstream thin film photov. Cigs is made through deposition a thin layer of copper indium gallium and selenium on glass or plastic and with electrodes on the front and back to collect electricity. Flexible lightweight and powerful.

The p type layer can be produced by thin film deposition of a gallium doped copper indium selenide cigs nanopowder sold under the ae solar energy group. Copper indium gallium diselenide solar cells nrel has significant capabilities in copper indium gallium diselenide cigs thin film photovoltaic research and device development. Gse manufactures copper indium gallium diselenide cigs by using state of the art controlled co evaporation and the thinnest stainless steel substrate possible to create flexible and light weight thin film pv products for use in any application. 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.

By brad mattson special to solar power world one of the most interesting and controversial materials in solar is copper indium gallium selenide or cigs for short. Cigs based thin film solar modules represent a high efficiency alternative for large scale commercial solar modules. Cigs based photovoltaic cells pv cells for solar energy composed of a positively charged or p type cigs layer underneath a negatively charged or n type layer are most commonly prepared by rapid thermal processing. It was part of a solar thin film hype cycle where some cigs companies such as solyndra nanosolar and miasolé almost became household names.
