Cigs solar panel recycling.

Cdte thin film panels are made from several thin layers. Doe national renewable energy laboratory summary. Then the shredded material is crushed further in the hammer mill. Strategies for recycling of solar panels date.

One main energy producing layer made from the compound cadmium telluride and surrounding layers for electricity conduction and collection. In cdte and cigs panels the materials are separated using a mainly chemical process. In the first solar recycling process warranty and end of life modules are collected to be shredded with manufacturing scrap. Recycling solutions for these non silicon based pv are based on recycling techniques from waste water treatment or battery recycling for example.

Recycling of copper indium gallium diselenide cigs solar cell materials is important to ensure future supply of indium and gallium. July 16 2020 source. 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.
