China Made Breakthrough in Research of Solar Panels’ Recycling

China State Grid Qinghai Provincial Electric Power Company disclosed on the 10th that China has achieved a major breakthrough in the recycling of solar panels. It has developed a resource recovery device and proposed a new environmentally friendly recycling process for solar panels, which has full independent property rights.
 
 In recent years, China ’s new and cumulative photovoltaic installed capacity is the world ’s first. Although it has the production technology of the entire photovoltaic industry chain, the solar cell resource recycling industry has lagged behind in terms of industrial layout, recycling technology research, and standard construction. European and American countries. Kang Jun, deputy dean of the Electric Power Research Institute of the State Grid Qinghai Provincial Electric Power Company, introduced that early research found that the decommissioning process of decommissioned solar panels is relatively primitive, it is easy to produce waste liquid and waste gas, and it is impossible to effectively separate valuable components and consume energy. At the same time, there are higher environmental risks.

 
 It is understood that most of the retired solar panel photovoltaic modules can be recycled and have considerable recycling value.  "Developed a resource recovery device for solar panels based on the hydroelectric effect, forming a new environmentally friendly recycling process for battery panels," said Song Baipeng, an assistant researcher in the high-voltage teaching and research department of the School of Electrical Engineering, Xi'an Jiaotong University. "After nearly two years of technical research and systems Research, tens of thousands of pulse discharge experiments, we finally got optimized power supply parameters. "  According to reports, through the application of new technology, neither chemical reagents nor waste water or waste liquid are generated during the recovery process. At the same time, dust pollution is avoided, the recycling process is harmless, and the effective separation and separation of different components are achieved. Enrichment can realize selective dissociation and recovery of different components such as glass, metal and silicon powder.
 
 Kang Jun said that in the future, the recycling process will be further optimized and upgraded, and a demonstration industrialized production line with a certain scale will be established. The standardized process for recycling solar panels based on the hydroelectric effect will be developed to improve the recovery efficiency and yield of high-value materials and solve the actual industry. The technical and management difficulties that may arise in production lay the foundation for large-scale market promotion and application.
