Solar photovoltaic industry in the whole chain, solar cells and components in a central position. In recent years, a large number of the introduction of foreign advanced equipment in the high-end and at the same time have a single crystal silicon, polycrystalline silicon, amorphous silicon, such as species of batteries and components, solar photovoltaic cells and components of the production is rising year after year. In 2007, China’s output of solar photovoltaic components for more than 1000MW, the first production has been largest in the world, more than Japan, the United States and other countries.
However, as the downstream part of the industrial chain business of solar modules an awkward position: the minimum profit margin, the greatest risk. According to an anonymous corporate vice president of solar energy components, the components of the current photovoltaic net profit margin of only about 5%. While in the international financial crisis, the polysilicon prices have fallen sharply,dell laptop battery, and corporate profits have begun to gradually upgrade, but the lower reaches of the solar cell system, the shrinking demand, leading to production decline, the profits of enterprises have begun to decline.
Another component of business risk in its biggest dilemma. There is a potential trade rules, it is the quality of solar energy components in the 20 years to 25 years, but we know not only the use of solar silicon material components, but also use different types of chemical materials, the durability of each material period is different, how to ensure that all of the material to achieve the 20 years to 25 years of shelf life, this is a big problem.
Components of solar energy vis-à-vis enterprises, enterprises of solar cells are relatively better at. First, the solar cell business relative to higher profit margins, it is up to 15%. Second, the solar cells is crystalline silicon material,inspiron 6000 battery , which is relatively small risk. Since the components of the technical content of cells is relatively lower, so the solar cells of domestic enterprises will not only produce solar cells and the production of components, which enhance the profits and reduce risk is undoubtedly of great role.
One effort to improve the conversion efficiency of solar cells. We can see that China’s solar photovoltaic cells and components of the technology and equipment has a lot of development and progress, photoelectric conversion efficiency of 10 percent from the original 12% to 17% ~ 18%. It is reported that Nanjing, China Light and Power has been successfully developed an average of 17.5 percent conversion efficiency as high as the SE inspiron 9300 battery, as well as 19% of the N-type batteries.
Second, the extension of industrial chain, reduce business risk and improve profits. China’s solar cells will produce the basic components of enterprises, and gradually began to penetrate the production of crystalline silicon, the industry chain to penetrate the most upstream. Suntech is the first production of crystalline silicon solar cells and modules have already infiltrated the high-purity polycrystalline silicon, silicon thin-film solar cells and solar photovoltaic power generation systems. Linyang energy from solar cells and components into the silicon material,inspiron 6400 battery , solar photovoltaic power generation systems in areas such as Shanghai have begun to solar ultra-day of its industrial chain to the upper reaches of the infiltration.
However, because of China’s solar cells and PV modules to export-oriented,inspiron e1505 battery, thus the current industry components over the infiltration of the industry chain mainly travel to a temporary facing downstream market penetration of the problem could not be opened. However, with the countries of the importance of energy-saving emission reduction, the PV market in China will also open, so many businesses to penetrate to the lower reaches as the technical reserves, ready to be launched.
With the maturing of photovoltaic technology, as well as the growing problem of energy shortage, the prospects of photovoltaic technology is bound to be bright. While the international financial crisis, the more cold photovoltaic enterprises, but for the entire industry, is also a reshuffle is conducive to rational norms of the market gradually. After 2009,latitude x300 battery,dell gd761,dell 6y270 ,latitude cpi battery ,latitude d510 battery, dell 310-6321, dell 310-6322 the “winter”, perhaps next year, solar energy photovoltaic industry will usher in Sunny.
