From September 16 to 18, the 2026 Green and Low Carbon Expo & International Engineering Construction Expo, themed "Green Blueprint, 'Carbon' Exploring the Future", was grandly held in Tianjin. Tongwei showcased its innovative achievements across the entire photovoltaic new energy industrial chain, presenting products and cutting-edge technological results including high-purity polysilicon, high-efficiency cells, and TNC series modules, to jointly explore new paths for green transformation with industry peers.

Tongwei's Full Photovoltaic New Energy Industrial Chain Booth

At this exhibition, Tongwei built a complete exhibition matrix covering "polysilicon - cell - module - terminal", fully demonstrating the collaborative innovation strength of the new energy full industrial chain. In the upstream of the industrial chain, high-purity polysilicon products attracted widespread attention. The self-developed "Yongxiang Process" production technology has been iterated to the 8th generation, with the 9th generation already in reserve. Its product quality, comprehensive technical indicators, and production capacity scale have reached the international leading level, and the global market share of high-purity polysilicon has ranked first in the world for many consecutive years .

As the core exhibition area of this expo, Tongwei TNC 3.0 Light-Harvesting Series Modules have become a "hit product" at the exhibition site. As an application solution for high bifacial scenarios with ground reflection potential, Tongwei TNC 3.0 Light-Harvesting Modules have undergone process upgrades on the basis of TNC 3.0 high-efficiency modules. Authoritatively certified by TÜV Rheinland, its maximum bifaciality can reach 93.07%, achieving major technological breakthroughs in mass production conversion efficiency and bifacial power generation performance . Benefiting from Tongwei's self-developed 360° three-dimensional passivation cell technology, the TNC 3.0 Light-Harvesting Module has an excellent low temperature coefficient (-0.26%/℃), and adopts a 4-split technology, which effectively reduces the operating temperature of the module and delays the aging of the packaging system. The first-year attenuation rate is controlled within 1%, and the annual linear attenuation rate is optimized to 0.35%, ensuring the stable operation of the power station .
