Breakthrough in key materials manufacturing in the photovoltaic industry

The reporter from Sinochem New Network News learned from the Baotou Municipal Economic and Trade Commission on March 23 that the manufacturing technology problem of silicon wafer cutting line, which has long plagued the development of China's photovoltaic industry, has been overcome. The first silicon wafer cutting line production line with independent technology in China is in the process. Baotou Yingboite Superhard Composite Materials Co., Ltd. was officially put into operation, and the qualified rate of cutting products reached over 96%, which is higher than the qualified rate of 93% of foreign companies. Wafer cutting lines are important raw materials for the manufacture of solar photovoltaic cells. After more than two years of technical research and innovation, Baotou Yingboite Superhard Composite Materials Co., Ltd. invested 150 million yuan to build a complete production line of 10,000 tons/year solar cell wafer cutting line in Baotou Equipment Manufacturing Industrial Park. The first batch of solar cell wafer cutting lines produced was put into use in Inner Mongolia Shantui New Energy Company. The results show that the technical performance indicators of the products have reached the international advanced level, and the cutting pass rate is over 96%. At present, InBlot's wafer cutting line device has entered the official production stage. Experts told reporters that the solar cell cutting line is used to cut silicon rods into solar cell wafers. A cutting line has a total length of 680 kilometers and can cut 4,500 to 5,000 solar cells, but the unit length can only be cut once. Consumables. The cutting pass rate is a key indicator to measure the performance of the silicon wafer cutting line, and the high pass rate can reduce the silicon material consumption. Due to the difficulty in manufacturing technology of cutting machine, its core technology has been monopolized by a few companies in Switzerland, Japan and other countries. Therefore, the solar cell cutting lines used in China all rely on imports, which seriously restricts China's semiconductor lighting, photovoltaic, integrated circuit manufacturing. And other industry development. The commissioning of InBlot's wafer cutting line project can lower the domestic market price of the product, meet the requirements of the photovoltaic industry for high performance, high precision, high efficiency and low price of raw materials, reduce the processing cost of silicon wafers, and thus reduce solar cells. The cost of production will promote the rapid development of China's photovoltaic industry.
It is reported that Baotou Yingboite Superhard Composite Materials Co., Ltd. was established in September 2009. It is a high-tech enterprise integrating scientific research, production and sales of silicon wafer cutting lines. Relying on the professional level and mature technology in the field of metal materials, and relying on the location advantages of silicon materials in Inner Mongolia, InBev has sprung up in the domestic PV industry and successfully developed new technologies for solar wafer cutting lines.
