Cigs Solar Cell Efficiency

Cigs cells also use the toxic chemical cadmium.

Cigs solar cell efficiency.

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. A novel multi junction solar cell was presented using two layers of copper gallium diselenide cgs and copper indium gallium diselenide cigs as the absorber and buffer layers respectively. Cigs cells traditionally have been more costly than other types. Now three records have been broken by two different devices including one that pushes the highest overall solar conversion.

Cigs thin film solar cells have reached 21 7 percent efficiency in laboratory settings and 18 7 percent efficiency in the field making cigs a leader among alternative cell materials and a promising semiconducting material in thin film technologies. Unlike most thin film solar technologies cigs solar panels offer a potentially competitive efficiency to traditional silicon panels. A cigs layer has a tunable bandgap which made cigs semiconductor the appropriate choice for design the solar cell. Because the material has a high absorption coefficient.

Cigs solar cell with ibc structure and up to 19 7 efficiency scientists in the netherlands have demonstrated an interdigitated back contact copper indium gallium selenide solar cell with a sub. This direct bandgap material can absorb a significant portion of the solar spectrum enabling it to achieve the highest efficiency of any thin film technology. A tunable bandgap allows the possibility of tandem cigs devices. 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.

The institut foton rennes and imn nantes propose a ph d. Solar cells are constantly improving on the road to maximum efficiency. The benefits of cigs solar cells include. Cigs based thin film solar modules represent a high efficiency alternative for large scale commercial solar modules.
