Cigs Solar Panel Recycling

In the solar world them s fightin words.

Cigs solar panel recycling.

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 cdte and cigs panels the materials are separated using a mainly chemical process. Because the material has a high absorption coefficient. In the first solar recycling process warranty and end of life modules are collected to be shredded with manufacturing scrap.

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. Unlike most thin film solar technologies cigs solar panels offer a potentially competitive efficiency to traditional silicon panels. From dispersed installations it is estimated to be 10 to 12 w.

Cigs cells also use the toxic chemical cadmium. Researchers have conducted the first global assessment into the most. Then the shredded material is crushed further in the hammer mill. 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.

Most efforts related to solar panel recycling concentrate on si panels and aim to recover and recycle the most important parts. Therefore the total cost of recycling in smelters thin film pv modules or scrap from large installations is 4 to 5 w. 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. The booming solar industry is in the midst of an argument over which material will become dominant in the future for harvesting sunlight.

Doe national renewable energy laboratory summary. The projected cost of collecting and transporting thin film solar panels from dispersed installations is about 8 to 10 w 5. 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. On average about 90 of a silicon based pv module can be recycled per input weight by pv cycle.

Strategies for recycling of solar panels date. 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. Recycling of copper indium gallium diselenide cigs solar cell materials is important to ensure future supply of indium and gallium.
