An Indian research group has used three different chemicals instead of commonly used hydrofluoric acid to separate silicon from the cell. The technique is claimed to be able to deliver recycled silicon with a purity of up to 99.9984%.Scientists from India's KPR Institute of Engineering and Technology have developed a new technique to recycle pure silicon from solar cells at the end of their lifecycle. Unlike other conventional methods to recycle silicon from PV devices, the new technique is not based on the use of highly toxic chemical hydrofluoric acid, which is commonly utilized in the PV industry ...Den vollständigen Artikel lesen ...
