Cigs Solar Panel Recycling

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.

Cigs solar panel recycling. Then the shredded material is crushed further in the hammer mill. 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. First solar is an american company that works in the cadmium telluride solar panel manufacturing space. Cis family solar panel manufacturers.

Companies involved in cis solar panel production a key thin film panel technology. Certain processes also use upstream shredding to access the materials more easily. 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. This process was originally based on the recycling of cadmium telluride cdte modules but will now be applied to the recycling of cigs modules.

In the present work we further develop high temperature chlorination separation using ammonium chloride. July 16 2020 source. 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.

One main energy producing layer made from the compound cadmium telluride and surrounding layers for electricity conduction and collection. 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. Doe national renewable energy laboratory summary. Strategies for recycling of solar panels date.

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. Cdte and cigs cover 7 of the photovoltaic market 5 of cdte panels and 2 of cigs panels irena 2016. Recycling solutions for these non silicon based pv are based on recycling techniques from waste water treatment or battery recycling for example. 44 cis panel manufacturers are listed below.

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