With the Sino-Japanese joint venture, Ning Jin Song 64 Taiwan Semiconductor Co., Ltd. Crystal Palace furnace production plant put into production, ningjin Hi-Tech Park has a single-crystal silicon furnace to reach 136 units, to become the world's largest solar silicon production base. In 2003, the park produced a total of nearly 600 tons of solar silicon, accounting for more than 70% of the national total, accounting for 20% of world market share.
Ningjin silicon Park is Ningjin County Electric Power of Hebei University of Technology as the basis, in 1996, created in production and research base. 7 years, the base of large diameter silicon solar results of carbon-oxygen as the carrier, the implementation of technological innovation, and prospering enterprise and brand strategy, total investment of nearly 3 billion yuan, has built three joint ventures and four Silicon supporting related businesses to form a single crystal silicon drawn as the center, choice of materials, quartz crucible, graphite parts, roll grinding, slicing, heavily-doped arsenic, phosphorus, antimony and other industrial chain of high-tech industrial parks, and to have two sets world's most advanced line of cutting machines and 55 sets Slicer inner circle to become China's largest silicon processing center, improve efficiency, reduce costs, enhance the enterprise anti-risk ability. In 2003, the park produced a total of nearly 600 tons of single crystals, accounting for more than 70% of the national total, accounting for 20% of world market share, and annual output value of 450 million yuan and exports worth 28 million U.S. dollars, most products export Japan, United Kingdom , the United States and other countries.
In 2004, the park also depicts a more ambitious blueprint. Plans to invest 150 million yuan, and then on the 40 single-crystal furnace, 4 sets of imported cutting machine, single-crystal to achieve an annual output of 1,000 tons. By 2007, production reached 2,000 tons of silicon, sliced to reach 25 million to build research, production, processing, trade and services as a whole, the output value of over 10 billion yuan, profit and tax-Chao 2 billion Chinese silicon photonics industrial city.
Solar silicon is a semiconductor material, widely used in modern microelectronics field, electrical conductivity ranging between conductors and insulators. Solar silicon for its excellent electrical properties of materials and microelectronic devices by manufacturers of all ages, the field of modern microelectronics, one of the most important basic materials can be used as substrate material for solar cells, known as the modern green energy basis.
