Cigs Solar Cells

The objective is to collect that electron before it runs into something and is re absorbed called recombination.

Cigs solar 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. In a manufacturing environment that means 15 percent to. Cigs solar cells are made from a compound called copper gallium indium diselenide sandwiched between conductive layers. 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.

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. 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. Because the material has a high absorption coefficient. 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.

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. These solar cells are commonly known as a copper indium gallium diselenide cu in x ga 1 x se 2 or cigs cells. Nrel is pursuing new materials for inclusion into the cell structure that will meet these requirements. The absorber the cigs layer in a solar cell is where the action is.

Nrel has the ability to deposit all layers of cigs thin film solar cells from 1 5 by 1 5 in. Here the light is absorbed and through the photovoltaic effect an electron hole pair is created. Although laboratory scale cell efficiencies have exceeded 20 commercial cigs modules typically have efficiencies between 12 and 14.
