Yinchuan, Ningxia: strive to break through 70 billion of photovoltaic silicon industry at the end of the 14th five-year Plan

At a press conference on the high-quality development of Ningxia's new materials industry held on February 11, Yinchuan Mayor Zhao Xuhui said that during the 14th five-year Plan period, Yinchuan will focus on key areas such as photovoltaic silicon, sapphires, third-generation semiconductors, graphite and graphene materials, energy storage batteries and energy storage materials, and strive to create hundreds of billions of new materials industry clusters. To build an influential global sapphire manufacturing base, a new silicon capital for photovoltaic materials in the country, and a new base for semiconductor materials in the west.

At present, Yinchuan has initially formed a development pattern of the whole industry chain from monocrystalline silicon to photovoltaic products, from sapphires to smart terminals, from semiconductor materials to integrated circuits, and from graphene to lithium-ion kinetic energy batteries. In the field of photovoltaic materials, it has the production capacity of 95GW single crystal silicon rods, 23GW silicon wafers and 10GW single crystal cells, and the production scale of single crystal pull rods and chips is in the leading level in the country. In the field of sapphire materials, it has formed an annual production capacity of 5500 tons of sapphire crystal and 9.6 million pieces of 4-inch sapphire substrate, and the largest industrial sapphire production base in the country is beginning to take shape. In the field of semiconductor materials, 6.7 million small-size semiconductor silicon wafers and 7.8 million large integrated circuit silicon wafers have been formed, and the construction of the whole industrial chain of single crystals, silicon components and silicon carbide has been accelerated. In the field of graphite and graphene materials, graphene ternary cathode materials and conductive pastes and lithium-ion power batteries form a linkage between the upstream and downstream of the industrial chain. Sinosteel, Graphite Science and Technology High Purity Graphite and graphene series industrialization projects are being centrally built, and the industrial cluster effect is emerging.

This year, Yinchuan will lay out and implement a number of major industrial chain supporting projects, such as Baofeng annual production 100GWh battery and energy storage container system demonstration, Xin Jingsheng 3500 tons of industrial sapphire crystal manufacturing and processing, Chuangsheng 400000 pieces of more than 4-inch third-generation semiconductor silicon carbide, crystal ring 12 million pieces of sapphire wafer cutting, grinding and polishing, and so on. It is estimated that the output value of the new materials industry will reach 33 billion yuan by the end of this year.

Next, at the end of the 14th five-year Plan, Yinchuan will strive to break through 70 billion in the photovoltaic silicon industry, 10 billion in the sapphire industry, 10 billion in the third-generation semiconductor industry, 80 billion yuan in energy storage batteries and materials, and 3 billion yuan in graphite and graphene materials. Yinchuan Economic Development area and Su Yin Industrial Park have been built into "hundreds of billions" parks respectively.
