Double Record! Tongwei Sets Records for Both TNC-G12 66 and TNC-G12R 66 Modules
On December 25, Tongwei PV R&D Center announced that, following certification by TÜV, the Tongwei TNC-G12 66 module achieved a front-side power of 763.4W at the standard size of 2384*1303mm, surpassing similar modules on the market by approximately 40W, with a conversion efficiency reaching 24.58%. Meanwhile, the TNC-G12R 66 module, at a size of 2382*1134mm, achieved 663.5W and a conversion efficiency of 24.56%, setting new records for power and efficiency in two mainstream TOPCon module formats.
Tongwei Gene: Technological Innovation at the Core
TOPCon technology is one of Tongwei's core innovations. The PECVD technology developed and led by Tongwei has filled a critical gap in the industry, leading to breakthroughs and advancements in TOPCon cell manufacturing. In 2023, this technology was featured as the cover article in the renowned scientific journal Progress in Photovoltaics (PIP), gaining widespread international recognition and citations. By Q4 2024, PECVD technology captured 56% of the global market share across 852GW of solar cell production capacity (according to InfoLink Consulting).
Tongwei's TNC technology has also garnered multiple prestigious awards, receiving recognition from both the industry and society. In 2023, Tongwei's "High-Efficiency Silicon Passivated Contact Solar Cell (TNC) Technology" was included in the 2023 Photovoltaic Industry Innovation Achievements Directory by the China Photovoltaic Industry Association, becoming the only TOPCon technology selected. In 2024, Tongwei’s self-developed "High-Efficiency N-Type TOPCon Solar Cell" was awarded recognition as a "First Set of Major Technical Equipment" in Sichuan Province, marking a breakthrough for solar technology in the region.
Through innovations like tubular PECVD poly deposition, Poly finger, EPT passivation, and ultra-fine printing, combined with optimized breakthroughs in the optical and electrical design of modules, Tongwei’s R&D team has successfully enhanced the power and efficiency of two key products: the TNC-G12 66 and TNC-G12R 66 modules.
