Cigs Solar Panels

The differences between cigs and crystalline solar cells.

Cigs solar panels.

Cigs based thin film solar modules represent a high efficiency alternative for large scale commercial solar modules. Just recently polycrystalline cigs achieved higher efficiencies than polycrystalline silicon with a world record of 20 8 compared to 20 4 for silicon. Cigs is the only technology that offers this promise. The manufacturing of these solar panels began in germany during 2011 but they are now also made in the united states and china.

Thin film solar panels made with a copper indium gallium selenide substrate contain less toxic cadmium than cdte cells. Eterbright utilizes cigs cu in ga se technology in its solar panels because of the numerous advantages of this innovative process. It opens up the possibility of the holy grail in solar. Silicon like efficiencies at low thin film costs.

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. For example cigs can be deposited on substrates such as glass metal foils and polymers. The measurement means that. Copper indium gallium selenide cigs.

Cigs will start earlier in the morning and stay on for longer in the evening. These advantages include high conversion efficiency low costs of manufacturing the ability to fully utilize a wide range of wavelengths of sun light and therefore retain efficacy in overcast conditions and. One big difference is that the cigs is more light sensitive and therefore will a 100 watt peak cigs panel produce around 10 15 more power in a year than a 100 watt peak crystaline panel. 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.

With efficiencies exceeding 20 measured in the laboratory there may be a continuing place for high efficiency cigs panels in the general solar panel market. Unlike most thin film solar technologies cigs solar panels offer a potentially competitive efficiency to traditional silicon panels. Because the material has a high absorption coefficient.
