Cigs Solar Panel Recycling

In the solar world them s fightin words.

Cigs solar panel recycling.

The projected cost of collecting and transporting thin film solar panels from dispersed installations is about 8 to 10 w 5. On average about 90 of a silicon based pv module can be recycled per input weight by pv cycle. Because the material has a high absorption coefficient. But recently the company was able to recycle 96 creating a new silicon panel recycling record.

Unlike most thin film solar technologies cigs solar panels offer a potentially competitive efficiency to traditional silicon panels. In the first solar recycling process warranty and end of life modules are collected to be shredded with manufacturing scrap. From dispersed installations it is estimated to be 10 to 12 w.

In cdte and cigs panels the materials are separated using a mainly chemical process. 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. This process was originally based on the recycling of cadmium telluride cdte modules but will now be applied to the recycling of cigs modules. Researchers have conducted the first global assessment into the most.

The booming solar industry is in the midst of an argument over which material will become dominant in the future for harvesting sunlight. 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. Most efforts related to solar panel recycling concentrate on si panels and aim to recover and recycle the most important parts. Strategies for recycling of solar panels date.

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. 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.
