en.Wedoany.com Reported - Tongwei's THC-G12 heterojunction copper interconnect module, under standard module dimensions (2384*1303mm), achieved an output power breakthrough of 802.43W and a total area conversion efficiency of 25.83%, as certified by the international authoritative organization TÜV Rheinland. This marks the twelfth time this series has set a new industry power record since its launch.

This record stems from Tongwei's application of copper interconnect metallization technology, achieving 100% silver-free heterojunction modules. On the cell side, industry-first technologies such as three-split manufacturing, back polishing, ultra-fine copper grid line technology, and edge optimization technology were adopted, advancing cell efficiency. On the module side, technologies including busbar-free interconnection, ultra-high screen-to-body ratio design, ultra-high-throughput light utilization, and ultra-low-loss line transmission were employed to enhance light utilization efficiency and reduce transmission losses.

This result was officially announced during the 2026 Shanghai SNEC International Solar Photovoltaic and Smart Energy Conference. TÜV Rheinland Greater China Senior Vice President of Solar and Commercial Product Services and Senior Vice President of Global Power Electronics Product Services, Li Weichun, presented the test certification certificate to Tongwei on-site, verifying module power, efficiency, and reliability indicators.
