Cigs Solar Panel Recylcing

Unlike most thin film solar technologies cigs solar panels offer a potentially competitive efficiency to traditional silicon panels.

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. Researchers have conducted the first global assessment into the most. 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. 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.

Strategies for recycling of solar panels date. Quantifiable recyclable materials in cigs solar modules the calculations of the viability of recycling are based on a 1 m 2 solar module. 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.

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. Research points to strategies for recycling of solar panels by national renewable energy laboratory due to rapid increase of pv installations over the past decade there is expected to be an explosion of retired pv modules by 2050. Abstract recycling of copper indium gallium diselenide cigs solar cell materials is important to ensure future supply of indium and gallium. Companies involved in cis solar panel production a key thin film panel technology.

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. Cigs cells also use the toxic chemical cadmium. 6 4. 44 cis panel manufacturers are listed below.

Doe national renewable energy laboratory summary. 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.
