Cigs Solar Panel Recycling

Researchers have conducted the first global assessment into the most.

Cigs solar panel recycling.

The two thin film solar cell technologies i e. 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. This process was originally based on the recycling of cadmium telluride cdte modules but will now be applied to the recycling of cigs modules. Strategies for recycling of solar panels date.

Recycling of copper indium gallium diselenide cigs solar cell materials is important to ensure future supply of indium and gallium. In cdte and cigs panels the materials are separated using a mainly chemical process. 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. In the first solar recycling process warranty and end of life modules are collected to be shredded with manufacturing scrap.

Solar panels a big industry that must take care about recycling the solar industry growth rates keep increasing every year across the world almost exponentially. Recycling solutions for these non silicon based pv are based on recycling techniques from waste water treatment or battery recycling for example. July 16 2020 source. In the present work we further develop high temperature chlorination separation using ammonium chloride.

44 cis panel manufacturers are listed below. Doe national renewable energy laboratory summary. Cis family solar panel manufacturers. However an industry that is proud to promote clean energy consumption and that is proud to be a sector concerned about climate change cannot forget to dispose properly of the.

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. Certain processes also use upstream shredding to access the materials more easily. Cdte thin film panels are made from several thin layers. 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.

Then the shredded material is crushed further in the hammer mill. In the cdte panels the semiconductor is formed by cadmium and tellurium and its efficiency increased from 15 4 in 2015 to 17 in 2016 which is comparable to that attained with poly. Companies involved in cis solar panel production a key thin film panel technology.
