The Status and Trends of Crystalline Silicon PV Module Recycling Treatment Methods in Europe and China

Abstract:

The disposal of PV systems will become a problem in view of the continually increasing production of PV modules. Development for waste PV modules recycling would be extremely effective in coping with this problem. In Europe, the thermal method and chemical method for PV recycling were deeply developed. The thermal treatment was to separate the module components under 600°C. The chemical treatment is to recover silicon wafers out of solar cells, which can be used again in modules. But automated separation of components and advanced chemical process needs to be studied on. In China, mechanical treatment research for PV recycling has just started. PV modules were separated and recycled by abrasive machining under the cryogenic condition and electrostatic separation. The mechanical treatment can't recycle silicon to reprocess new wafers for its low purity. Compared to the advanced technology in Europe, PV recycling in China is primary and badly in need of improving to face the huge PV module recycling demands in future.
