TONGWEI CO.,LTD(SH:600438) 中国能源报·2026-01-21 02:31Core Viewpoint - The article discusses the advancements in photovoltaic technology, specifically focusing on Tongwei's TNC 3.0, which aims to enhance efficiency in solar cells and modules to achieve lower levelized cost of electricity [1][2]. Group 1: Efficiency Improvement - Increasing module efficiency is essential for maximizing output per unit area, which is a key variable in optimizing the value of solar systems [2]. - The enhancement in efficiency leads to greater power generation capability per module, resulting in increased overall system efficiency and reduced costs for supporting materials like brackets and cables [5]. - The direction for efficiency improvement is clear: optimizing the ability of modules to capture sunlight, converting more light into electricity, and minimizing losses during current transmission [5]. Group 2: Multi-Slice Module Technology - Tongwei's focus is not only on immediate performance improvements but also on the long-term stability of efficiency in real-world applications [6]. - Multi-slice module technology has been a significant avenue for enhancing output per unit area, but challenges such as production efficiency and cutting damage must be systematically addressed [6]. - Since the establishment of the multi-slice high-efficiency module R&D project in 2016, Tongwei has made significant breakthroughs in R&D, production, sales, and downstream applications of multi-slice modules [6]. Group 3: Advanced Battery Technology - The TNC 3.0 G12R-66 model achieves a maximum power of 670W with a conversion efficiency of 24.8%, while the G12-66 model reaches 770W with the same efficiency, making it a leader in the industry for 210 modules [7]. - The efficiency gains in TNC 3.0 are not solely dependent on module processes but are built on the integration of multiple key technologies, including 360° passivation high-efficiency batteries [9]. - The 360° passivation battery technology allows for a significant increase in single-cell efficiency to over 26.3% and power output to over 11.6W, contributing to a power gain of over 26.4W for the TNC 3.0 module [10]. Group 4: Long-term Stability and Real-world Application - TNC 3.0 not only achieves improvements in experimental parameters but also establishes a foundation for long-term stable output under real manufacturing and operational conditions [10]. - The true efficiency revolution lies in ensuring that technological breakthroughs are consistently realized in every production cycle, making efficiency improvements a verifiable and sustainable competitive advantage for Tongwei [10].
