Innovation Empowerment: Continuously Breaking Records

Since the establishment of the Tongwei Global Innovation R&D Center in June 2024, the research team has made further advancements in core technologies such as passivation of heterojunction cells, coating improvements, and module 908 interconnection and high-throughput dense packing, successfully elevating the power output of heterojunction modules to a new level of 780W. This achievement also represents the second time the T6 workshop of the Tongwei Global Innovation R&D Center has set a new record for heterojunction modules.

Since first establishing a power record in January 2023, Tongwei's PV R&D team has enhanced the power output of heterojunction modules by over 60W and improved conversion efficiency by more than 2% through in-depth research into the integrated technology of heterojunction cell modules with in two years, marking the tenth record-breaking achievement in heterojunction modules.

R&D Pioneer: Driving the Future

As a pioneer in the field of heterojunction technology, Tongwei continues to drive technological innovation, injecting new momentum into industry development. In 2018, Tongwei was the first to invest in HJT technology, establishing the country's first GW-level HJT production line in 2021 and initiating the industry's first 210 half-cell HJT project development. In July 2022, Tongwei completed the development of the industry's first bifacial microcrystalline HJT cell. Tongwei has built a "cost reduction and efficiency enhancement" ecosystem through advancements in bifacial microcrystalline technology, copper interconnection without silver metallization, and 0BB module technology, collectively driving the large-scale production of HJT and continuously leading technological upgrades in the industry. Among these, the copper interconnection technology has formed an industry-leading THL solution capable of GW-scale production.

Tongwei has always aligned itself with national strategies, prioritizing technological innovation in its corporate development. The company has comprehensively deployed research and development in mainstream industry technologies such as TOPCon, HJT, xBC, and perovskite/crystalline silicon tandem cell and module technologies, achieving remarkable progress across multiple fronts. With its extensive R&D layout and robust innovation capabilities, Tongwei will continue to deepen its commitment to technological advancement, leading the industry's development and contributing to the global goals of carbon peak and carbon neutrality.
