Cigs Solar Panel Recylcing
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.
Cigs solar panel recylcing. July 16 2020 source. 6 4. Only the indium gallium and glass are considered in the calculations but the metal or plastic used in the frame and backing can also be recycled. Strategies for recycling of solar panels date.
Cis family solar panel manufacturers. 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. Companies involved in cis solar panel production a key thin film panel technology. Solar panels contain many different silicon cells thin film solar cells and crystalline silicon solar cells as well as cadmium telluride which is needed for recycling.
Most efforts related to solar panel recycling concentrate on si panels and aim to recover and recycle the most important parts. Our previous work includes recycling of selenium from cigs materials and a scoping study on high temperature chlorination for the separation of the remaining elements using different chlorination agents. If we don t mandate recycling many of the modules will go to landfill said arizona state university solar researcher meng tao who recently authored a review paper on recycling silicon solar. As stated above there are presently three different types of recycling process applied to solar pv panels which are physical thermal and chemical as illustrated in fig.
Researchers have conducted the first global assessment into the most. Cigs cells also use the toxic chemical cadmium. 44 cis panel manufacturers are listed below. Unlike most thin film solar technologies cigs solar panels offer a potentially competitive efficiency to traditional silicon panels.
Doe national renewable energy laboratory summary. 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.
