On June 12, 2025, during the SNEC International Photovoltaic Power Generation and Smart Energy Conference, LONGi Green Energy hosted a dedicated forum on "BC Technology Innovation and Industrial Synergy." As a key strategic partner of LONGi in the BC cell sector, Yingfa Ruineng Chairman Zhang Fayu was invited to join the panel discussion, "Building a BC Innovation Ecosystem Together." He shared Yingfa Ruineng's hands-on experience in advancing BC cell technology and reinforced the company's commitment to strengthening strategic cooperation with LONGi in the development of high-efficiency photovoltaic technologies.

During the forum discussion, Chairman Zhang Fayu expressed his appreciation for LONGi Green Energy's long-term strategic support. "As a global leader in the photovoltaic industry," he said, "LONGi has consistently embraced an open, win-win philosophy, driving technological innovation while safeguarding a healthy industrial ecosystem — setting a benchmark for sustainable development across the sector."

He highlighted that BC cell technology, with its exceptional conversion efficiency, superior anti-degradation performance, and distinctive aesthetic appeal, is emerging as a key engine for technological progress in the photovoltaic industry. Looking ahead, he called for joint efforts with industry partners to foster a healthy ecosystem that values innovation and protects intellectual property, continually unlocking innovation potential and building a solid foundation for the sustainable growth of BC technology.

In 2024, Yingfa Ruineng and LONGi Green Energy embarked on a 6GW BC cell partnership, engaging in deep collaboration across the entire value chain — from technology R&D and standards setting to process optimization and market applications — accelerating the commercialization of BC technology. Chairman Zhang Fayu emphasized that Yingfa Ruineng will continue to follow its strategy of "high quality, high service, high technology, rigorous internal control, and strong management," capitalizing on its expertise in precision operations, on-site management, and continuous innovation in high-efficiency cell manufacturing. By combining these strengths with LONGi's industry-leading capabilities in module production and global market expansion, the two companies aim to create a powerful strategic complement — building core competitiveness across the full industry chain from high-efficiency BC cells to complete module systems.

As strategic partners in BC technology, Yingfa Ruineng and LONGi Green Energy are dedicated to developing a BC product system with reliable quality across its full lifecycle and fostering an open, collaborative, and mutually beneficial industrial ecosystem — ensuring each BC cell delivers maximum value to customers.

Together, they are accelerating the transition of BC technology from laboratory innovation to large-scale commercial application, offering a more competitive "China Solution" for the global green energy transformation and jointly writing a new chapter in the high-quality growth of the photovoltaic industry.
