On September 17th, the major scientific and technological research project of Zhejiang Province, which was undertaken by Wenzhou Ruiyang Solar Materials Co., Ltd., “Research and Industrialization of EVA Film for High Power Photovoltaic Cells†was accepted by the Provincial Science and Technology Department in Hangzhou.
The experts of the jury decided that the "Ruifu" EVA film project was successfully developed, and the product performance has reached the international advanced level, especially the aging resistance has made a major breakthrough, ranking the world's leading level, meeting the service life requirements of photovoltaic modules. Finish It can replace the imported EVA film and realize the localization of high-performance EVA film. This also means that the self-manufacturing level of PV module materials in China has entered a new field.
It is understood that the life expectancy of photovoltaic modules is more than 25 years, and the aging resistance of current EVA films has become the bottleneck of the development of China's photovoltaic industry. To this end, China needs to import more than 1 billion high-performance EVA film every year, and it is often subject to high prices, long delivery days, and the supply cannot be guaranteed.
At the same time, the power generation efficiency of the components using the "Ruifu" EVA film is increased by 0.6% year-on-year. That is to say, with the same materials, the "Ruifu" film module can sell a few dollars more.
Wenzhou Ruiyang Solar Materials Co., Ltd. is a professional manufacturer of solar photovoltaic module EVA packaging film invested by Zhejiang Zhongli Group, with an annual output of 1.8 million m2. This project cooperates with DuPont, and after three years of research and development, it integrates international advanced manufacturing processes and has obtained many inventions.
