On September 25, the 2nd 0BB PV Cell & Module And Equipment Industry Chain Technology Forum, jointly hosted by Photovoltaic Industry Research and Changzhou Photovoltaic Industry Association, was held in Jiaxing, Zhejiang. The forum facilitated discussions on the future development direction of photovoltaic technology. Yan Dengzhou, Assistant Director of PV Technology Center of Tongwei Co., Ltd., was invited to deliver a keynote speech.

In his keynote speech titled *Tongwei High-Power TNC Products and Diversified Application Scenario Solutions*, Assistant Director Yan Dengzhou showcased Tongwei's latest R&D achievements. He noted that Tongwei began TOPCon R&D deployment in 2020, establishing the sector's first 210 PECVD Poly cell pilot line. The upcoming TNC 2.0 product in 2025 will solidify Tongwei's leading position in the N-type era with its cutting-edge technological prowess. As the cornerstone of high-efficiency products, 0BB technology enables Tongwei's mass-produced modules to reach 645W+, and coupled with the advantages of bifaciality, Tongwei's TNC 2.0 products possess strong market competitiveness.
