Joint innovation fuels new industrial forces in China


Chinese firms, including LONGi, have been leading the global solar market, providing over 80 percent of the photovoltaic modules. LONGi's groundbreaking research and development (R&D) has set records in photovoltaic technology. The Heterojunction Back Contact solar cell, independently developed by LONGi Green Energy, has achieved a cell conversion efficiency of 27.09 percent, setting a new world record for monocrystalline silicon solar cell efficiency. Experts say BC battery technology will become the absolute mainstream of crystalline silicon batteries in the next five to six years.

Experts point out that the photovoltaic industry chain is transforming into new productivity. The formation of new productivity requires joint innovation from upstream and downstream enterprises in the industry chain. Diamond wire is essential for silicon wafer cutting in the photovoltaic industry. As an upstream supplier to the photovoltaic industry, Yang Ling Metron New Materials has become one of the world's largest diamond wire manufacturers. Not only does it master a complete set of core technologies, but its products also account for nearly half the global diamond wire market share. Its products are also constantly innovating, resulting in the cost of photovoltaic electricity dropping by more than 80 percent in the past 10 years.

"High investment in R&D contributes to the entire industry and society. Longi has always talked about persisting in doing difficult and right things for a long time. For example, the first lighthouse factory we built in the global photovoltaic industry uses green manufacturing to create more customer and social value," LONGi's vice president, Zhang Haimeng, told CGTN.
