Cigs Solar Cell Efficiency

Solar cells are constantly improving on the road to maximum efficiency.

Cigs solar cell efficiency.

Copper indium gallium diselenide solar cells nrel has significant capabilities in copper indium gallium diselenide cigs thin film photovoltaic research and device development. Subject about the development of high efficiency epitaxial cigs silicon tandem solar cel. The claimed conversion efficiency improves on the 24 6 the researchers announced in september 2018 for a perovskite based tandem cigs solar cell the imec press office told pv magazine. Cigs cells traditionally have been more costly than other types.

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. The institut foton rennes and imn nantes propose a ph d. A cigs layer has a tunable bandgap which made cigs semiconductor the appropriate choice for design the solar cell. 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.

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. The benefits of cigs solar cells include. Cigs cells also use the toxic chemical cadmium. A tunable bandgap allows the possibility of tandem cigs devices.

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. 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. Cigs based thin film solar modules represent a high efficiency alternative for large scale commercial solar modules. Because the material has a high absorption coefficient.

Now three records have been broken by two different devices including one that pushes the highest overall solar conversion.
