Solar cells have been classified as electronic waste in the revised Waste Electrical and Electronic Equipment (WEEE) Directive published by the European Union in July 2012 . Therefore, the problem of the electronic waste generated by scrapped solar cells cannot be ignored. Solar-cell scrap and cumulative scrap in China in 2005–34
As early as 2012, the latest revision of the EU Waste Electrical and Electronic Products Management Regulations took the lead in bringing solar PV modules into the scope of management. Solar cells are officially classified as electronic waste and require efficient recycling [24, 25].
The initial phase of solar cell recycling involves the collection and transportation of used panels to recycling facilities. Upon arrival, panels undergo careful disassembly, and various components such as glass, metals, and semiconductors are sorted and separated .
Solar-cell scrap and cumulative scrap in China in 2005–34 Recycling and reuse of complete cells are very difficult and the recycling of large amounts of aluminium, silver, silicon and other resources in waste cells will become the focus.
Therefore, the recovery and purification technologies of metals in crystalline-silicon solar cells need to go beyond the laboratory and further towards the development of industrial application. The mechanical treatment method uses physical methods, such as crushing and sorting, to separate the components and then reuse them.
