Chan Ye Xin Xi Wang·2026-02-13 03:30Core Viewpoint - The solar diffusion furnace industry in China is experiencing significant growth, with the market size expected to reach 6.05 billion yuan by 2025, reflecting an 11% year-on-year increase, driven by the expansion of the photovoltaic industry and supportive government policies [1][6]. Industry Overview - Solar diffusion furnaces are essential for producing crystalline silicon solar cells, specifically for forming PN junctions, which are critical for enhancing cell efficiency [2]. - The main types of solar diffusion furnaces are vertical and horizontal, each offering distinct advantages in terms of production efficiency and space utilization [2]. Industry Chain - The upstream of the solar diffusion furnace industry includes quartz components, heating systems, temperature control systems, and gas control systems, with quartz components being crucial for stability and efficiency [3]. - The midstream involves the manufacturing of solar diffusion furnaces, while the downstream primarily serves the photovoltaic industry, specifically in solar cell and module production [3]. Current Development - The solar diffusion furnace market is benefiting from China's commitment to renewable energy, with solar power generation capacity increasing significantly from 204.2 GW in 2019 to an expected 1,161.2 GW by the end of 2025, marking a 41.90% year-on-year increase [4][5]. - The production of solar cells is projected to reach 83,274.3 MW by 2025, a 7.60% increase from the previous year, driven by government subsidies and technological advancements [5]. Competitive Landscape - The solar diffusion furnace industry has high entry barriers, making it difficult for new entrants to compete. Leading companies leverage technology, supply chains, and customer resources to maintain competitive advantages [7]. - Key players in the industry include North Huachuang, Jiejia Weichuang, and Jing Sheng Machinery, among others, with North Huachuang reporting a revenue increase of 32.97% year-on-year for the first nine months of 2025 [7][8]. Industry Trends - The rapid development of the solar diffusion furnace industry is leading to accelerated industry consolidation, with smaller companies lacking core technologies being phased out, while stronger companies invest in R&D and improve production processes [9]. - Domestic companies are increasingly focusing on international markets, expanding their presence through partnerships and participation in global trade shows, capitalizing on their competitive pricing and responsive service [10].
