BC电池有望实现“弯道超车”

Core Insights - The Chinese photovoltaic industry is experiencing a price recovery in the market for polysilicon, silicon wafers, battery cells, and modules, with year-on-year increases of 31.6%, 6.8%, 6.5%, and stable prices respectively as of January to September 2025. However, production volumes for polysilicon and silicon wafers have decreased by 32.8% and 12.5% respectively, while battery cell and module production have increased by 8.8% and 12.2% respectively [1] Group 1 - The photovoltaic industry is still in a period of transformation and deep adjustment, despite the positive price trends [1] - The BC battery technology is viewed as a key direction for future development in the photovoltaic market due to its higher efficiency and cost reduction potential [1] Group 2 - The current market competition is heavily focused on efficiency, with various technologies approaching their theoretical efficiency limits. BC batteries currently have a conversion efficiency of 27.5%, with a theoretical limit exceeding 29% [2] - The market share of PERC batteries has dropped to 11.2%, while TOPCon batteries dominate with a market share of 88.3%. BC batteries are expected to reach a market share of 10% by the end of 2025, indicating significant growth potential [3] Group 3 - Reducing costs is a major focus for the photovoltaic industry, with silver paste costs accounting for 27% of battery cell costs and 12% of total module costs as of December 2024 [4] - The rising price of silver has led to increased costs for high-temperature silver paste, prompting the industry to explore alternatives such as copper paste, which is cheaper and has better conductivity [4][5] Group 4 - Innovation is essential for the healthy and orderly development of the photovoltaic industry, with companies encouraged to accelerate technological innovation and improve product quality to strengthen their competitive edge [6]
