Cigs Solar Cells

Cigs solar cells are made from a compound called copper gallium indium diselenide sandwiched between conductive layers.

Cigs solar cells.

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. Because the material has a high absorption coefficient. The differences between cigs and crystalline solar cells. This material can be deposited on substrates such as glass plastic steel and aluminum and when deposited on a flexible backing the layers are thin enough to be allow full panel flexibility.

The objective is to collect that electron before it runs into something and is re absorbed called recombination. Although laboratory scale cell efficiencies have exceeded 20 commercial cigs modules typically have efficiencies between 12 and 14. 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. Here the light is absorbed and through the photovoltaic effect an electron hole pair is created.

In a manufacturing environment that means 15 percent to. Cigs solar cell in full copper indium gallium selenide solar cell thin film photovoltaic device that uses semiconductor layers of copper indium gallium selenide cigs to absorb sunlight and convert it into electricity although cigs solar cells are considered to be in the early stages of large scale commercialization they can be produced by using a process that has the potential to reduce. While it trails in efficiency cigs is not far away has shown a cigs solar cell that converts 19 5 percent of sunlight into electricity. Nrel has the ability to deposit all layers of cigs thin film solar cells from 1 5 by 1 5 in.

Cigs will start earlier in the morning and stay on for longer in the evening. 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. The absorber the cigs layer in a solar cell is where the action is.
