| 英文摘要: |
| This paper analyzed the materials and functions of each component in typical crystalline silicon solar panels. It reviewed the research progress on four recycling technologies for end of life crystalline silicon photovoltaic modules， namely physical， thermal， chemical and combined processes. It discussed the advantages and disadvantages， processing cycles， treatment costs and recycling benefits of these existing recovery technologies. In view of the current challenges， specifically the efficient and low pollution removal of ethylene vinyl acetate（EVA）encapsulant， the harmless disposal of fluorinated substances in the backsheet and the elimination of pyrolytic carbon residues from the surface of silicon cells， future research directions were proposed， including development of green and efficient recovery technologies， integrated application of multiple approaches to develop novel recycling processes and reduction of environmental pollution and energy consumption. |
