Tongwei's Heterojunction Module Power Breaks the World Record Again
2025-03-06

On March 5, Tongwei Co., Ltd. announced a Voluntary Disclosure Announcement Regarding the Heterojunction Module Power Breaking the World Record Again. According to the announcement, the THC210 high-efficiency heterojunction modules, developed by Tongwei's Global Innovation R&D Center, achieved a power output of 783.2W and a conversion efficiency exceeding 25.21% under the standard module size of 2384*1303mm, as verified by the international authority TÜV Rheinland. This achievement surpasses Tongwei's previous record and marks the eighth time the company has broken the world record for heterojunction module power.


As a prominent player in the PV industry, Tongwei Co., Ltd. prioritizes the security of information for both the company and its customers. This certification not only represents international recognition of Tongwei's information security management capabilities, but also signifies a significant milestone in the company's commitment to its Environmental, Social, and Governance (ESG) strategy. It further enhances Tongwei's credibility among investors and consumers, providing strong momentum for its sustainable development and global market expansion.


As a leader in the global PV industry, Tongwei Co., Ltd. has established a production capacity of over 900,000 tons of high-purity crystalline silicon, over 140GW of high-efficiency solar cells, primarily N-type, and 85GW of high-efficiency solar modules. In line with the national "carbon peaking and carbon neutrality" goals and the "strengthening the nation through science and technology" strategy, Tongwei Co., Ltd. places technological innovation at the forefront of its development. The company has comprehensively deployed R&D in mainstream technologies, including TOPCon, HJT, xBC, perovskite/crystalline silicon tandem cells and modules, with an average annual R&D investment exceeding RMB 3 billion in recent years. To further integrate technological innovation resources and continuously explore advanced and cutting-edge technologies in the crystalline silicon PV industry, the company has dedicated to building its Global Innovation R&D Center, which has commenced operations in June 2024. This center aims to be a key driver for the company in mitigating risks, identifying new directions, precisely positioning the market, and leading R&D trends over the next 5-10 years and beyond.

The Global Innovation R&D Center currently focuses on research directions including high-efficiency crystalline silicon cells and materials, high-efficiency and high-reliability modules, PV testing and analysis, and new technologies. It specifically concentrates on core and cutting-edge technology development in areas such as TNC, THC, TBC cells and modules, copper interconnect metallization, perovskite/silicon tandem solar cells, and novel PV modules. Simultaneously, it is dedicated to the analysis and characterization of materials and devices, as well as reliability testing and evaluation of module products. The center has established an integrated heterojunction copper interconnect and perovskite cell workshop with the largest workshop area, highest production capacity, and strongest upgradeability in the industry. It also boasts the industry's largest single-area, most comprehensive testing projects, and most intelligent and automated module reliability laboratory, providing solid hardware support for the company's R&D efforts.


In the field of heterojunction technology, Tongwei Co., Ltd. has long been an industry pioneer, continuously promoting technological innovation. In 2018, Tongwei initiated the layout of heterojunction technology in the PV sector; in 2021, it built the first GW-level heterojunction pilot production line in China and launched the industry's first 210 half-cell heterojunction project development; in July 2022, it completed the development of the industry's first double-sided microcrystalline heterojunction cell R&D line. Currently, Tongwei has constructed a "cost reduction and efficiency increase" ecosystem with three dimensions: double-sided microcrystalline technology, copper interconnect silver-free metallization, and 0BB module technology, and has formed an industry-leading overall solution for GW-scale mass production in copper interconnect technology. The company's long-term and profound technical accumulation in the heterojunction field has laid a solid foundation for the company's THC210 high-efficiency heterojunction module power to once again break the world record, and will continue to promote the large-scale mass production of heterojunctions in the future, leading the technological upgrade of the PV industry.


This latest world record for heterojunction module power demonstrates Tongwei's extensive expertise in the research and development of cutting-edge PV technologies, particularly heterojunction technology. This achievement will further strengthen the company's established comprehensive competitive advantages in the PV industry and actively contribute to the realization of China's and the world's carbon peaking and carbon neutrality goals.
