Cigs Solar Panel Recycling

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.

Cigs solar panel recycling.

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. One main energy producing layer made from the compound cadmium telluride and surrounding layers for electricity conduction and collection. Then the shredded material is crushed further in the hammer mill. The two thin film solar cell technologies i e.

In cdte and cigs panels the materials are separated using a mainly chemical process. Strategies for recycling of solar panels date. Cis family solar panel manufacturers. Researchers have conducted the first global assessment into the most.

July 16 2020 source. This process was originally based on the recycling of cadmium telluride cdte modules but will now be applied to the recycling of cigs modules. First solar is an american company that works in the cadmium telluride solar panel manufacturing space. Doe national renewable energy laboratory summary.

44 cis panel manufacturers are listed below. Certain processes also use upstream shredding to access the materials more easily. 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. 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.

In the first solar recycling process warranty and end of life modules are collected to be shredded with manufacturing scrap. In the present work we further develop high temperature chlorination separation using ammonium chloride. 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. Companies involved in cis solar panel production a key thin film panel technology.

Cdte and cigs cover 7 of the photovoltaic market 5 of cdte panels and 2 of cigs panels irena 2016. 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 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.
