On October 30, the PV Technology Center at Tongwei Co., Ltd. announced a remarkable breakthrough: after rigorous testing by TÜV, an authoritative certification agent, its independently developed THC 210 heterojunction module achieved a record-breaking maximum output power of 776.2 watts and a photoelectric conversion efficiency of 24.99% at a size of 2,384*1,303mm. This milestone, marking the first heterojunction module to surpass the 775-watt threshold, is the ninth record set by Tongwei in power and efficiency since 2023.

Tongwei's intelligent manufacturing production line of high-efficiency modules

Tongwei prioritizes research and development, elevating innovation to unprecedented heights

Technological R&D stands as a core competitive advantage, driving the company’s growth and development. The opening of Tongwei’s Global Innovation R&D Center in June heralds a new era in its commitment to research and development. This heterojunction module record shines as a beacon in Tongwei’s tapestry of innovation. Within just four months, the R&D team successfully enhanced the efficiency of heterojunction cells by nearly 0.3%, leveraging advanced light-trapping structures, PECVD uniformity optimization, high-mobility target materials, and fine-line printing techniques, with power of mainstream modules reaching 745 watts. Based on the milestone of mass production verification of advanced heterojunction cell technology, the heterojunction module has reached a new pinnacle in power performance. With an industry-leading, GW-scale heterojunction + copper interconnection (THL) solution, Tongwei continues to push the boundaries of silver-free heterojunction modules, further spearheading the development of cutting-edge industry technologies.
