Swedish researchers have developed a method to recycle valuable metals from flexible thin film copper-indium-gallium-diselenide (CIGS) solar cells under mild leaching conditions. They showed that 100% of silver and 85% of indium can be recovered after 24 hours of leaching at room temperature using two moles of nitric acid.Scientists from Chalmers University of Technology in Sweden have shown how to recycle valuable metals like silver (Ag) and indium (In) from flexible CIGS solar cells using mild leaching conditions. They used 15.6 cm2 x 15.6 cm2 flexible CIGS solar cells with an Ag conductive ...Den vollständigen Artikel lesen ...
