In the field of energy, all manufacturers of semiconductors, business opportunities are expanding. Because, if we can make full use of semiconductor devices and systems can improve energy efficiency. VGP-BPS8 VGP-BPS8A VGP-BPS9
Solar energy is inexhaustible renewable energy rights. Is it as clean energy, produces no pollution of the environment. The effective use of them in solar energy use in large solar photovoltaic energy in recent years is the fastest growing, most dynamic sector of research, is one of the most watched items. To this end, people have developed a solar cell. The solar cells are mainly based on semiconductor materials, its principle of operation involves using photovoltaic materials absorb light energy in the conversion took place after the photoresponse, according to the different materials used, types of solar cells are also different, but whatever the material to produce batteries on the general requirements of solar cell materials are: 1, material bandgap semiconductors can not be too wide to be more photoelectric conversion efficiency of: 3, the material itself does not cause pollution to the environment, and 4, a material suitable for mass production and properties of materials stable.

China is the world’s largest solar cell manufacturing base. Chinese production of polycrystalline silicon solar cells are essentially the main raw material for polycrystalline silicon. Compared to thin film solar cells, polycrystalline silicon photovoltaic solar cells more efficient. thin film solar cells is usually not more than 10%, while most of polycrystalline silicon for solar cells over 14%. A few years ago, because of lack of polysilicon materials, the international market price of polysilicon as much as several hundred dollars per ton. In this context, many parts of China has launched a production line of polycrystalline silicon. From excess capacity, combined with the financial crisis, the price of polysilicon has followed a sharp fall. Monitoring, polysilicon and other emerging industries is that “overlapping orientation of the building.” At the same time, the process for producing polysilicon for high energy consumption, and silicon tetrachloride and other toxic by-products of environmental pollution, has also had many critics. As products of China polysilicon solar cells are mainly exported to developed countries, it was strongly called “consumption abroad, including pollution. ” Wake-up in the polycrystalline silicon solar cells on occasion, solar cells, another member of the family – thin film solar cells to light.

The solar cell industry in China was even in the production of crystalline solar cells, driven by rapid expansion, in fact, the cells of the China Film Si and CIGS thin film solar such as development, we can also say positive. Involved in the production of thin film Si solar cells of almost 60 companies. Who not only possess technology companies, but also a set of (Turn-Key) to import equipment to start enterprises. In recent years, cells thin film solar production to increase at high speed. According to research firm DisplaySearch market published in the August 11 reports changes in production capacity of solar cells in 2009, thin film solar cell production capacity of approximately 3.58 million kilowatts. We can name implies, stacks of thin films is preparing a film on solar cells, because of its very small amount of silicon, and therefore easier to cut costs. thin film solar cells is one of energy-efficient products, but also easier to combine with the building. GD761 Y9943 FK890 Raw material of silicon on the international market in the context of continuing tension, thin film solar cells has become the international trends of PV market development and hot spots. broad prospects for thin film solar cells, but does not mean no risk. At present, the thin film solar cell solar cell industry in China, the proportion of only about 10%. The next 10 years to 20 years, thin film solar cells will not occupy the dominant position of solar cells, because the technology is not mature enough.
Although our beginning in 2007 to become the global production of solar cells than any other country, but abroad there are many gaps. In addition, new types of solar cell development, we are still in its initial phase, many foreign sources of development and thus my long way to go solar cell development. GK479 3R305
