Development trend of monocrystalline silicon wafer
In addition, it is conducive to the healthy development of the photovoltaic industry, is conducive to photovoltaic products into millions of households."LDK LDK is a high-tech photovoltaic enterprise focusing on the research and development, production and sales of solar polysilicon material, ingot and polycrystalline silicon wafer. NYSE Listed Companies in 2008 to achieve sales revenue is expected to reach $1 billion 750 million. The photovoltaic business and become the world's first to enter the "GW club". Total orders exceeded 13GW, becoming the world's largest polysilicon suppliers in hand orders.
LDK LDK is committed to the development of a solar polysilicon materials, ingots and silicon chip R & D, production, sales as one of the world's leading PV enterprises". In the field of polysilicon, polysilicon LDK LDK project to establish a closed-loop circulation system of the most advanced production technology, and all components of waste will be recycled, not only cost savings, but also protect the environment, to solve the biggest bottleneck in polysilicon production technology. After the project is put into production, the cost control will be far beyond the current level of production in China to reach the international advanced level. This will be China's most promising in the environment, scale, cost, quality and other aspects of the overall success of the silicon material project. By 2009, LDK LDK is expected to become the world's leading production capacity of the largest, most technologically advanced, most environmentally friendly process of polysilicon and solar wafer production base. The first practical photovoltaic slicing machine was born in 1980s, it originated from the research and work of Dr. Charles Hauser. Dr. Charles Hauser is the founder of the Swiss HCT slicing system, which is now the predecessor of the application materials company PWS precision silicon wafer processing system division. These machines use a cutting line with a slurry to complete the cutting action. Today, the main structure of the silicon ingot and wafer cutting machine is still based on the original Charles Dr. Hauser machine, but the processing load and cutting speed has been significantly improved.
Speaking of silicon, we have to mention Chinese LDK! The world's largest manufacturer of solar wafers - Jiangxi LDK LDK Solar Co. Ltd., announced in September 20, 2008, the company has been successful in the United States on a day before the issuance of 4 million 800 thousand shares of American Depositary Shares (ADS), for the price of $41.75, to raise funds of $200 million, mainly for polysilicon plant and wafer factory expansion.It is reported that LDK LDK will use 60% of the net proceeds of the issuance of the company to support the construction of polysilicon plant, the use of polysilicon to expand the production capacity of 30%, for the general business activities of 10%.
The development of science and technology is driving the development of semiconductors. With the development of automation and computer technology, the cost of this kind of high technology product of silicon chip (integrated circuit) has been reduced to a very low level. The price of a mini computer is only a few hundred yuan. This paved the way for the computer to enter thousands of households. Make our life more and more modern.Of course, the changes in the chip to the family is far more than that, with the increase in the number of electronic households, a new production lifestyle - "home industry" and "home office" is being produced. In the future, sitting at home operating machines, command production and management companies and factories, will become a reality The day is not too distant when.
