Yunnan Province issued "Yunnan Province's 14th five-year Plan for the Development of Raw material Industry" to build and improve the green silicon industry system.

On December 27, the Department of Industry and Information Technology of Yunnan Province issued the "Yunnan Province's 14th five-year Plan for the Development of Raw material Industry" (hereinafter referred to as "Development Plan"), which clearly defines the development goal of the province's raw material industry: Yunnan will rely on the advantage of green energy. speed up the construction of a modern raw material industrial system to create a "China Green Aluminum Valley" and a "photovoltaic capital". By 2025, the main business income of the province's raw materials industry above scale will exceed 850 billion yuan, and strive to achieve an average annual growth rate of more than 10%.

In terms of development priorities, the "Development Plan" points out that it is necessary to build and improve the green silicon industry system. Guided by the national strategy and market demand, focusing on "silicon photovoltaic, silicon chemical industry, silicon electronics" and other subdivisions, strive to break through the key core technologies and processes of the silicon-based material industry, and vigorously develop and promote high-end, high-quality and efficient technology products. promote the green silicon industry in Yunnan Province to the middle and high end. Priority is given to making up the silicon photovoltaic industry chain, with the goal of improving the conversion efficiency of Shenchi photovoltaic industry, focusing on the research and development of key technologies and equipment of high-purity silicon, high-efficiency and large-size single crystal silicon wafers used in the photovoltaic industry, and breaking through the core technology of high-efficiency single crystal products. To improve the thinning and efficiency of products, introduce downstream photovoltaic modules, photovoltaic cell production and other deep processing enterprises, and establish a complete photovoltaic glass, frame, silver paste, high purity graphite, high purity quartz, inverter and other silicon photovoltaic industry supporting system, basically build a "photovoltaic capital". Focus on the construction of the silicon chemical industry chain, rely on the silicone projects under construction in the province, carry out the construction and development of related industrial chains around silicone products, and actively introduce advantageous enterprises to develop silicone-based materials such as silicone resin, silicone rubber and silicone oil and downstream processing products, so as to build the whole industry chain of silicon chemical industry. Vigorously cultivate the silicon electronics industry chain, rely on Yunsi intelligent town, actively cultivate and introduce electronic-grade polysilicon, silicon carbide and other silicon electronic materials production and processing enterprises.

The Development Plan proposes that by 2025, major breakthroughs will be made in the transformation and upgrading of the province's raw material industry, creating a number of large enterprises with industry level and a number of domestic benchmark enterprises. a number of new material innovation clusters with reasonable layout, distinctive characteristics and strong influence will be formed to realize the historic leap of the development of the province's raw material industry.

The main business income of the province's above-scale raw materials industry has exceeded 850 billion yuan, and strive to achieve an average annual growth rate of more than 10%. Among them, the main business income of new materials exceeded 120 billion yuan. The efficiency of raw material industrial enterprises above large scale in the province has been greatly improved, the profit margin of main business income has reached the average level of industrial enterprises, and the utilization rate of smelting capacity of major metals is more than 75%. The conversion rate of in-situ primary processing of non-ferrous metals reached 50%, and the conversion rate of intensive processing reached more than 25%.
