Cigs Solar Cell Efficiency

Cigs based thin film solar modules represent a high efficiency alternative for large scale commercial solar modules.

Cigs solar cell efficiency.

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

The institut foton rennes and imn nantes propose a ph d. 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. Unlike most thin film solar technologies cigs solar panels offer a potentially competitive efficiency to traditional silicon panels. Because the material has a high absorption coefficient.

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

Cigs cells also use the toxic chemical cadmium. 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 benefits of cigs solar cells include. Copper indium gallium diselenide solar cells nrel has significant capabilities in copper indium gallium diselenide cigs thin film photovoltaic research and device development.

A tunable bandgap allows the possibility of tandem cigs devices.
