Chan Ye Xin Xi Wang·2025-12-30 01:53Core Viewpoint - The N-type TOPCon solar cell technology is rapidly evolving, with significant growth in production and market share expected in the coming years, driven by its advantages over P-type cells and increasing investments from Chinese photovoltaic companies [1][4]. Group 1: Industry Overview - TOPCon cells utilize a tunneling oxide passivated contact structure, enhancing charge transport and energy conversion efficiency compared to traditional P-type cells [2][4]. - The global shipment volume for TOPCon cells is projected to reach 565.2 GW in 2025 and 652.7 GW in 2026, with significant growth also expected for Xbc and HJT cells [1][4][6]. - In China, TOPCon cell shipments are anticipated to grow from 534.6 GW in 2025 to 609.1 GW in 2026, reflecting a strong domestic market for N-type technology [1][6]. Group 2: Technological Advantages - TOPCon cells offer higher conversion efficiency, better performance in low-light conditions, and reduced degradation compared to P-type cells [3][4]. - The production process for TOPCon cells involves additional steps compared to PERC, but it results in lower costs and higher potential for premium pricing [3][4]. Group 3: Industry Development History - The development of TOPCon technology can be categorized into four phases: initial technology formation (2015-2017), product layout (2018-2020), commercial promotion (2021-2022), and explosive growth (2023-present) [8]. Group 4: Competitive Landscape - Major companies in the N-type TOPCon sector include JinkoSolar, Tongwei, JA Solar, Trina Solar, and others, all of which have begun large-scale production of N-type TOPCon cells [10][11]. - Yingfa Energy is recognized as a leading manufacturer with a significant market share, achieving a production capacity of 32.7 GW and a revenue of 35.4 billion yuan from N-type TOPCon cells in 2024 [10][11]. Group 5: Future Trends - The N-type technology is expected to dominate the market, with increasing penetration rates and a shift towards cost reduction and diverse application scenarios [14]. - The industry is likely to see accelerated technological breakthroughs and a concentration of production capacity as it moves towards a clearing phase [14].
