Perhaps one day, MP3 is no longer needed batteries laptop battery, on the roads that people can simply charge cable plugged into a fixed interface, clothing, MP3 can be smooth and unimpeded hearing. To participate in the meeting, reporters were no longer worry about the laptop battery, as long as the laptop to face any light source, can be unlimited use. Perhaps one day the road no longer need petrol cars can run, high-rise buildings no longer need a large substation, and even every household can be redundant electricity sold to the national grid. This is all because of this new solar thin-film battery technology. as MP3, notebook computers, high-rise buildings facades, auto body and highways covered on both thin-film solar cells when sunlight will be transformed for the steady flow of power to change our lives.

All this sounds like the future world of the picture, but the reality is to us. Long been engaged in solar cell research the Great Wall Securities researcher Zhou Tao introduced in July, Legend IBM 40Y6793 Battery Capital has just raised the fourth new fund injection Zhejiang Advanced solar energy company in a thin-film solar battery production .10 at the end, Intel CEO Paul Otellini announced three investment plans, which invested 20 million U.S. dollars investment in thin-film solar cell development, and manufacturing and solution provider, Shenzhen Chuang Yi Technology .11 5 Japan, the World Bank Group member IFC announced that it will the new Chinese New Austrian Austrian Solar Energy Group Limited 136 million U.S. dollars to build a large-scale thin-film solar module production line.

In the capital markets, venture capital companies has always been a profit-driven vane, in the context of the global financial crisis, why they set their sights on solar thin-film batteries?

Zeng Xiang-Bo Chinese Academy of Sciences Institute Semiconductors told reporters that the human dream of long ago can be obtained directly from the energy required sunlight, solar cells are also the birth of a number of years, but the traditional IBM FRU 92P1125 Battery crystalline silicon solar cells have been because of high cost , photoelectric conversion rate is low, the shape of restricted but not large-scale promotion.

Recently, the reporter went to Beijing Fangshan Qinglong Town, see the installation of at least thousands of street lights solar street lamp. Local villagers told reporters, here is the "solar model" typical construction. It is said that Shidu, Changyang, Qinglong, etc. 19 towns and 69 villages along the main roads 8 are equipped with solar lights, yard lamp, landscape lamp.

Fangshan District Energy Office introduced the use of solar street lighting, just build two hours a day of solar energy, can use a whole night. A lamp can be used for 18 years, can save 60,000 kwh electricity, saving electricity 40 thousand yuan above. region 7000 solar street light, 18-year electricity savings of 280 million yuan.

A curious reporter asked the local villagers, as so many energy-saving, why not large-scale promotion. Villagers told reporters that this solar street light well, but the fresh IBM FRU 92P1121 Battery stuff is too expensive, and an ordinary street lamp solar street price several times, if even the the good days are rainy days, this street is not so, and it lights every few days to bad, one night, this road a quarter of the streetlights that are not.

Zhou Tao told reporters that these solar lights are used in conventional crystalline silicon cells. This cell processing technology is complex, requiring advanced equipment to use for purification of silicon, and only purified to 99.9999% of the crystalline silicon can Compaq Armada M700 Battery be used to produce solar cells. this process of high-precision, high-energy consuming high cost of traditional solar cells. but silicon raw material prices soared in recent years, from 2003 to 30 U.S. dollars / kg risen in 2008 to 500 U.S. dollars / kg, almost rose 16 times. In addition, crystalline silicon purification technology has been monopolized by foreign makers, although there the country will also be able to produce, but production is very low, in 2007 the domestic production of crystalline silicon have 1,000 tons, but the gap was up to 1 million tons.

Take some parts of the solar street lamps, the Zhou Tao is estimated that the cost of ordinary lamps about 2,000 yuan, while the solar street lamps of up to 8,000 yuan. And the price savings compared to high construction costs make it hard to accept in many places. In addition, Traditional solar street lamp switch circuit controller in frequent, it is also very easy to Compaq EVO N400c Battery damage.
