Driven by global carbon neutrality goals and clean energy popularization policies, the global photovoltaic industry has maintained a high-speed development trend in 2026. Major photovoltaic manufacturing enterprises in Asia, Europe and the Middle East are accelerating the expansion of TOPCon and HJT high-efficiency cell production lines, and gradually eliminating backward PERC production capacity. The technological upgrading of photovoltaic cells not only improves the photoelectric conversion efficiency of solar panels, but also puts forward more stringent requirements for supporting high-temperature processing equipment and core consumable materials. Graphite thermal field components, as the key core materials of photovoltaic cell diffusion, sintering and film-forming equipment, directly determine the processing temperature uniformity and product yield of photovoltaic cells, and are the key guarantee for high-efficiency photovoltaic cell production.
Different from traditional industrial graphite products, photovoltaic special graphite components have extremely strict technical indicators. First, ultra-high purity is required, and trace metal impurities in graphite will cause cell surface contamination and reduce photoelectric conversion efficiency, so the total impurity content needs to be controlled below 50ppm. Second, excellent high-temperature dimensional stability is required. Long-term high-temperature circulating operation cannot produce deformation or warpage, to ensure the precision of cell processing. Third, uniform internal structure and low porosity are required to avoid local temperature difference affecting cell consistency. Fourth, excellent thermal shock resistance is required to adapt to frequent temperature rise and fall cycles of photovoltaic equipment and extend the service life of consumables.
With the large-scale commissioning of new photovoltaic production lines, the global market demand for photovoltaic special graphite thermal field components has shown explosive growth. Industry data shows that the global market size of photovoltaic special graphite products will maintain a compound annual growth rate of 29% from 2026 to 2030. At present, the global supply capacity of high-quality photovoltaic-grade graphite components is extremely limited. Most ordinary graphite manufacturers cannot meet the ultra-high purity and precision processing requirements of the photovoltaic industry, resulting in a serious market supply gap. Many overseas photovoltaic equipment manufacturers face the problem of insufficient supply of core graphite consumables, which restricts the production capacity release of high-efficiency photovoltaic cells.
In terms of market competition, the photovoltaic special graphite industry has high technical barriers. It needs long-term accumulation in raw material purification formula, high-temperature graphitization process and precision machining technology. At present, the global high-end market is occupied by a few leading enterprises, and the market concentration is extremely high. With the continuous expansion of global photovoltaic capacity, the order demand for high-quality photovoltaic graphite components continues to increase, and the market gap is further enlarged, bringing huge development opportunities for professional photovoltaic graphite suppliers.
Jincheng Graphite has long focused on the research and development and production of photovoltaic special graphite components, and has accumulated rich technical experience in the field of high-purity photovoltaic graphite materials. The enterprise has independently developed a secondary ultra-high temperature purification process, which effectively removes trace metal impurities in graphite raw materials, and controls the total impurity content of photovoltaic-grade graphite products below 30ppm, far exceeding the international industry standard. By optimizing raw material particle gradation and pressing forming process, the product has uniform internal structure, low porosity and excellent thermal stability, fully adapting to the harsh working conditions of photovoltaic high-temperature processing equipment.
In terms of product series, Jincheng Graphite has formed a complete product system covering photovoltaic graphite heating plates, heat insulation plates, sintering trays, diffusion furnace graphite components and special-shaped fixing parts. The enterprise can carry out customized design and processing according to the equipment parameters and technological requirements of different photovoltaic production lines, and provide matching product performance test reports and application technical guidance. The photovoltaic special graphite products produced by Jincheng Graphite have the advantages of long service life, stable batch performance and high processing precision, which can effectively improve the production yield of photovoltaic cells and reduce the equipment maintenance cost for customers.
At present, Jincheng Graphite's photovoltaic-grade graphite products have been exported to Europe, Southeast Asia, the Middle East and other major photovoltaic manufacturing regions, providing stable supporting materials for many international photovoltaic equipment manufacturers and cell production enterprises. Facing the continuous growth of the global photovoltaic market, the enterprise is expanding the production capacity of photovoltaic special graphite products, and continuously optimizing product technology according to the iteration of photovoltaic cell technology, to meet the increasingly stringent material requirements of the global high-efficiency photovoltaic industry.
