On December 25, Tongwei PV Technology Center at Tongwei Co., Ltd. announced a remarkable achievement in PV innovation. Following rigorous testing by TÜV, a globally recognized certification body, Tongwei's TNC-GI 2-66 and G12R-66 modules, two mainstream TOPCon models, have set new records in power output and efficiency. At a standard size of 2384 x 1303 mm, the TNC-GI 2-66 module achieved an impressive front-side power output of 763.4 watts — approximately 40 watts higher than comparable products currently available in the market — and a conversion efficiency exceeding 24.58%. At a standard size of 2382 x 1134 mm, the G12R-66 module delivered a front-side power output of 663.5 watts, also about 40 watts above similar products on the market, with a conversion efficiency surpassing 24.56%.

1. Technological innovation embedded in Tongwei's DNA

TOPCon technology stands as one of Tongwei's core advancements. Under Tongwei's leadership in R&D efforts, PECVD technology has redefined industry standards, achieving groundbreaking milestones in TOPCon solar cell manufacturing. In 2023, this innovation was prominently featured on the cover of the prestigious PV journal Progress in Photovoltaics (PIP) and garnered widespread global recognition in the industry. By Q4 2024, Tongwei's PECVD technology has captured a commanding 56% market share of the 852 GW global solar cell production capacity (source: InfoLink Consulting).

In addition, Tongwei's TNC technology has earned numerous accolades from the industry and society for its exceptional innovation. In 2023, Tongwei's "High-efficiency Silicon Passivated Contact Solar Cell (TNC) Technology" was successfully selected into the 2023 PV Industry Innovation Achievement Recommendation Catalog issued by the China Photovoltaic Industry Association (CPIA), as the only TOPCon cell technology in the industry. This recognition highlights its pioneering innovation and market leadership. In 2024, TW Solar's independently developed High-Efficiency N-Type TOPCon Solar Cell achieved a groundbreaking milestone by being recognized as "Sichuan Province's First Set of Equipment in the Corresponding Technological Field." This prestigious recognition marks a transformative "zero-to-hero" breakthrough, establishing it as the first solar cell technology to earn a place on "Sichuan Province's List for the First Set of Equipment in the Corresponding Technological Field."

The Tongwei PV R&D team leveraged cutting-edge innovations such as tube PECVD Poly deposition, Poly finger technology, EPT passivation, and fine-line printing, alongside advancements in optical and electrical design. These efforts propelled Tongwei's mainstream products — TNC-G12-66 and TNC-G12R-66 — to set new benchmarks in module power and efficiency.
