Solar power is receiving increasing attention as a renewable energy source that can help mitigate the effects of climate change. The life of solar panels is generally about 25 years, and more and more solar panels are discarded after reaching their useful life, which has become an urgent environmental problem to be solved. At present, many waste solar panels are landfilled, which will cause environmental pollution.
Xinhua News Agency, Tokyo, September 8 (Reporter Qian Zheng) Japan's "Photovoltaic Recycling Association" recently issued a press release stating that the association has cooperated with two photovoltaic companies to recycle raw materials from waste solar panels and successfully trial-produced them using recycled materials. New solar panels. This closed-loop recycling method will help solve the environmental problems caused by discarded solar panels.

The communique said that after the research and development team removed the aluminum frame of the waste solar panel, it heated the solar panel with high-temperature water vapor generated by the thermal decomposition equipment developed by Japan's new solar energy company. The sealant and resin sheet of the panel will sublimate in the water vapor environment of more than 600 degrees Celsius, and the remaining glass plate can be recycled. In addition, the silver, silicon, copper and other raw materials used in the battery board can achieve high purity recovery.
The "Mingu Production Institute", an enterprise engaged in the production of solar panels, uses recycled raw materials to trial-produce new solar panels and confirms that they can generate electricity normally.
Min Gu Changhao, head of the solar energy division of Mingu Production Institute, said that the R & D team finally confirmed that recycled raw materials can be used to make solar panels like ordinary raw materials.
The communique said that after the successful trial production, the R & D team hopes to use this technology to realize the application and mass production of closed-loop recovery of solar cell modules within five years.
