On September 15, the 2026 International Digital Energy Exhibition (IDEE·SZ) officially kicked off at Shenzhen Convention & Exhibition Center (Futian). Tongwei made a high-profile appearance with innovative achievements across the entire new energy industry chain, showcasing flagship products including high-purity polysilicon, high-efficiency cells, and TNC 3.0 high-efficiency modules. With its robust technical strength and integrated full-industry-chain advantages, it drew extensive attention from exhibitors and merchants at home and abroad.

At the exhibition site, Tongwei's high-efficiency cells have garnered widespread industry attention thanks to their excellent mass-production performance. From a technical perspective, Tongwei has achieved a module power gain of over 10W through the iterative upgrading of technologies such as TPE and Poly Tech. Among them, the Poly Tech technology can also increase the bifaciality by more than 5%, enhancing the power generation performance of modules in multiple dimensions.

Based on this technical foundation, the TNC 3.0 product has achieved further breakthroughs: while fully integrating the above technologies, it innovatively moves the slicing process to the cell manufacturing end, effectively reducing process losses, improving the core performance of cells, and providing strong support for value release at the module end. At present, the conversion efficiency of modules adopting this technical route has exceeded 26.3%, opening up broader value-added space for high-efficiency modules. From TNC 1.0 to TNC 3.0, Tongwei has continuously promoted the iterative upgrading of the TNC series products, constantly improving product efficiency, scenario adaptation capability and full-cycle application value.

Exhibition Guests Learning About Tongwei High-Efficiency Cells

The TNC 3.0 series modules are undoubtedly the "star products" at the exhibition. Adopting a 4-split design, the product boasts a maximum module efficiency of 24.8%, a maximum power of 770W for the G12-66 format, a temperature coefficient as low as -0.26%/℃, and a maximum bifaciality of 93.07%. Its internal circuit adopts a high-redundancy design, which significantly improves the shading resistance and long-term power generation reliability under complex working conditions, bringing higher power generation revenue and better levelized cost of energy for large-scale ground power stations and distributed photovoltaic projects. It is worth mentioning that Tongwei TNC series modules have repeatedly won authoritative recognition for their excellent quality, having been awarded the Kiwa PVEL "TOP PERFORMER" honor for consecutive years, and obtaining the "Ultra-Long-Term Stable and Reliable Operation" certificate from China National Photovoltaic Quality Inspection Center, with its reliability strength widely affirmed by the industry.

Tongwei High-Efficiency Modules Attract Exhibitors and Merchants to Stop and Learn About Them

From being a global leader in high-purity polysilicon, to continuous breakthroughs in cell technology, and then to the value upgrading of module products, this exhibition not only serves as a centralized display of Tongwei's technological innovation achievements, but also a demonstration of its strength in facilitating global energy transition. In the transition period when the industry is shifting from scale expansion to value creation, Tongwei is providing a more certain "Tongwei Solution" for global energy transition through in-depth integration of the entire industry chain and continuous technological innovation.
