Copper Indium Gallium Selenide Cigs Thin Film Photovoltaic Solar Panels

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.

Copper indium gallium selenide cigs thin film photovoltaic solar panels.

Cigs based thin film solar modules represent a high efficiency alternative for large scale commercial solar modules. It was part of a solar thin film hype cycle where some cigs companies such as solyndra nanosolar and miasolé almost became household names. 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. Flexible lightweight and powerful.

A copper indium gallium selenide solar cell is a thin film solar cell used to convert sunlight into electric power. Copper indium gallium selenide cigs solar cell is a thin film solar cell which is used for converting sunlight into electricity. Copper indium gallium selenide cigs is a ternary semiconductor used as a a p type or absorber layer material in solar cells. Because the material has a high absorption coefficient and strongly absorbs sunlight a much thinner film is required than of other semiconductor materials.

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. Cigs is one of three mainstream thin film photov. 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. 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.
