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.

Cigs solar panel recycling.

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. Then the shredded material is crushed further in the hammer mill. 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. On average about 90 of a silicon based pv module can be recycled per input weight by pv cycle.

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. This process was originally based on the recycling of cadmium telluride cdte modules but will now be applied to the recycling of cigs modules. Most efforts related to solar panel recycling concentrate on si panels and aim to recover and recycle the most important parts. July 16 2020 source.

Pv cycle a nonprofit dedicated to solar panel take back and recycling collects several thousand tons of solar e waste across the european union each year according to director jan clyncke. In cdte and cigs panels the materials are separated using a mainly chemical process. In the solar world them s fightin words. Therefore the total cost of recycling in smelters thin film pv modules or scrap from large installations is 4 to 5 w.

Doe national renewable energy laboratory summary. In the first solar recycling process warranty and end of life modules are collected to be shredded with manufacturing scrap. The projected cost of collecting and transporting thin film solar panels from dispersed installations is about 8 to 10 w 5. Recycling of copper indium gallium diselenide cigs solar cell materials is important to ensure future supply of indium and gallium.

But recently the company was able to recycle 96 creating a new silicon panel recycling record. Cigs cells also use the toxic chemical cadmium. 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.
