Recently, this reporter from Henan Xun Tianyu Technology Co., Ltd. was informed that the company’s construction of a 1000 tons polysilicon / year 4N ~ 5N-class solar grade polysilicon project of the main projects completed recently completed. The project is currently using proprietary technology to build one of the largest polysilicon production, which indicates that China will break into a long-term reliance on expensive imports of polysilicon passive situation is conducive to enhancing our polycrystalline silicon solar cells, semiconductors materials industry as a whole.

According to reports, polycrystalline silicon industry is a national “Eleventh Five-Year” period focus on supporting and developing high-tech industries, its products are widely used in semiconductor integrated circuits, solar energy industry in areas such as optoelectronics industry is the foundation for the development of circular economy material. At present, the domestic polysilicon products are very tight, the market gaps greater than 90% of the polysilicon products are imported from abroad at high prices come through.

It is understood that the lack of self-production technology, restricting the rapid development of China’s polysilicon industry, a key factor, once the technical problems are resolved, China’s polysilicon industry can grow, the domestic polysilicon market will not be then be controlled by others. At present, the polysilicon production technology are only a few countries in the world control and monopoly of domestic-owned enterprises would like to introduce the technology from abroad, but its core technology is still regarded as closed. To this end, domestic enterprises and research institutes have set up their own R & D team to carry out research and development polysilicon production technology research, and strive to take the road of independent innovation.

Xun Tianyu Technology polysilicon project, is used by the CAS Shanghai Institute of Technical Physics Purification of the physical development of polysilicon production technology. The process has a high quality and low cost characteristics of polysilicon production in China is expected to overcome the bottleneck for many years. In addition, the Nanyang City also has a silica-rich resources, has proven reserves of 50 million tons a conservative or more, and silica is the best basis for smelting polysilicon material. Nanyang Municipal Government and Shanghai Institute of Technical Physics decided to use their respective strengths to jointly build the largest polysilicon production base in the Central Plains.

According to reports, the project total investment of 1.7 billion, the annual design and production of 6,000 tons of solar grade polysilicon products, an annual output of 1,000 tons of 4N ~ 5N-class solar grade polysilicon project has been completed. Wait until the projects are all put into production, annual sales income of 60 billion, record profits of 2 billion yuan, production value of related industries led more than 200 billion yuan.

多晶硅将不再依赖于中国的进口

最近，这个来自河南迅天宇科技有限公司记者有限公司获悉，该公司的1000吨的多晶硅/年为4n〜为5N级太阳能级的多晶硅项目主体工程近日竣工落成。该项目目前正在使用的专有技术，以建立最大的多晶硅生产，一，表明中国将成为一个昂贵的进口多晶硅的长期依赖，打破被动局面，有利于加强我们的多晶硅太阳能电池，半导体材料产业作为整个。

据报道，多晶硅产业是国家“十一五”重点支持和发展高新技术产业的重点时期，其产品广泛用于半导体集成电路，太阳能领域，如光电产业行业是基金会的物质循环经济的发展。目前，国内多晶硅产品是非常紧张，市场缺口超过90％的多晶硅产品从国外进口高价才能通过。

据了解，缺乏自我生产技术，限制中国的多晶硅产业，一个关键因素，一旦快速发展的技术问题得到解决，中国的多晶硅产业成长，国内多晶硅市场将不会再被控制其他人。目前，多晶硅生产技术是世界上唯一的控制和国内的国有企业想引进国外的技术垄断，有几个国家，但其核心技术仍然被视为封闭。为此，国内企业和研究机构建立了自己的研发团队进行研究和开发的多晶硅生产技术研究，努力走自主创新之路。

迅天宇科技多晶硅项目，使用的是中国科学院上海技术物理研究所纯化的多晶硅生产技术的物理的发展。这个过程具有很高的质量和在中国的多晶硅生产成本低的特点，可望克服多年的瓶颈。此外，南阳市还拥有硅资源丰富，已探明5000万吨保守或以上，硅储量是冶炼多晶硅材料的最佳基础。南阳市政府和上海技术物理研究所决定利用各自的优势，共同建立最大的多晶硅中原生产基地。

据报道，该项目总投资1.7亿元，年设计和6000太阳能级多晶硅产品，比1000四倍体年产〜为5N级太阳能级多晶硅项目吨已经完成。等到项目全部投产，年销售收入60亿元，20亿元，相关产业生产值创记录的利润导致超过200亿元。08.11.5
