The Ministry of Industry and Information Technology issued the "Regulations on the Standardization of Photovoltaic Manufacturing Industry (Draft for Comment)", which stipulates the production layout, project establishment, production scale, process technology and energy consumption in the manufacturing fields of polysilicon, silicon wafers, batteries and components in the photovoltaic industry. The merger and reorganization of photovoltaic manufacturing industry and technological transformation will promote the healthy development of the photovoltaic industry. According to the "Conditions", Hebei Province will strictly control the photovoltaic manufacturing projects that newly expand production capacity in the production layout and project establishment, and build and renovate and expand photovoltaic manufacturing projects with a minimum capital ratio of 20; in terms of production scale, polysilicon The scale of each project is more than 3,000 tons/year, the annual production capacity of silicon ingot is not less than 1000 tons, the annual production capacity of silicon rods is not less than 1000 tons, the annual production capacity of silicon wafers is not less than 50 million pieces, and the annual production capacity of crystalline silicon batteries is not less than 200. The annual production capacity of MW, crystalline silicon battery components is not less than 200 MW, and the annual production capacity of thin film battery components is not less than 50 MW. At the same time, the annual cost of R&D and process improvement for PV manufacturing enterprises is not less than 3 and not less than 10 million yuan of total sales.
The "Conditions" also specifies the conversion efficiency of solar cells. The photoelectric conversion efficiencies of polycrystalline silicon cells and monocrystalline silicon cells are not lower than 16 and 17 respectively; the photoelectric conversion efficiencies of polycrystalline silicon battery modules and monocrystalline silicon battery modules are not lower than respectively. 14.5 and 15.5.
