Cigs Solar Cells

The absorber the cigs layer in a solar cell is where the action is.

Cigs solar cells. The differences between cigs and crystalline solar cells. Scientists from the university of luxembourg and portugal s international iberian nanotechnology laboratory have designed a new copper indium gallium and di selenide cigs micro solar cell. Because the material has a high absorption coefficient. 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.

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. 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. These solar cells are commonly known as a copper indium gallium diselenide cu in x ga 1 x se 2 or cigs cells.

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. Cigs will start earlier in the morning and stay on for longer in the evening. Cigs solar cells are made from a compound called copper gallium indium diselenide sandwiched between conductive layers. 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.

Nrel has the ability to deposit all layers of cigs thin film solar cells from 1 5 by 1 5 in. In a manufacturing environment that means 15 percent to. Although laboratory scale cell efficiencies have exceeded 20 commercial cigs modules typically have efficiencies between 12 and 14.
