The most expensive, most sophisticated, most complex conversion efficiency of solar panels to about 40%, which is only 40% absorption of sunlight can be converted into electricity. Scientists think that in the little room efficiency instead focus on reducing costs in the United States Idaho National Laboratory (INL) for a cheap, folding infrared solar panels, and the highest conversion efficiency up 80%.
The new panel is the key to the use of nano-technology. Its surface covered a nano-miniature antenna array, and add thickness of the 1000 atomic conductive metal wire can capture infrared radiation, even in the evening can also continue to work.
Nano-technology research in general are staying in the centimetre level, but INL go to the micron level, within each box integrates 260 million ultra-miniature antenna.
More commendable is that the use of the folding plastic materials also very easy to make, so scientists believe that this technology can be quickly out of the laboratory, and ultimately bring cheap and efficient solar power programme.
The only regret is that, while Nano antenna in the sun will release a great deal of electronic, but it's no way these electronic capture, output power is not. INL is the current practice in nanotechnology in the implantation of a miniature antenna capacitor, or AC / DC converters, which hopes to take the capture of energy, and will not increase costs, loss of efficiency.

China Solar Silicon Wafer Manufacturers In NYSE Listing
China solar silicon chip maker ZHEJIAN YUHUI ENERGY SOURCE CO,. LTD (ReneSola) on the 29th listed on the New York Stock Exchange. At this point, in New York Stock Exchange-listed Chinese mainland enterprises had reached 40.
ReneSola this to the price of 13 US dollars per share initial public offering of 10 million American Depositary Securities (ADS), financing 130 million US dollars.
ReneSola the board of directors and CEO Li Xianshou interviewed by reporters said the financing, the company alone, polysilicon films from the current capacity of more than 300 megawatts expanded to 645 megawatts, is expected to one of the world's top three silicon film producers as well. Li Xianshou expressed confidence in the future development of ReneSola. He said that the solar energy industry has great potential and that the landing ReneSola United States capital market, to raise development funds on the one hand, the other hand will also encourage companies improve their management level, and further expand the scale of production, the establishment of the industry's leading edge.
Two years ago, the London Stock Exchange in the United Kingdom ReneSola GEM successful fund-raising 50 million US dollars. Early last year, ReneSola in Hong Kong also successfully issued 120 million US dollars of corporate bonds, and further enrich the company's capital. Two years ago, the company registered capital of only 1.5 million US dollars, now ReneSola total investment of nearly 220 million US dollars, and the registered capital increased to 100 million US dollars.

United States Investment In Solar Power Plan
Rising oil prices and the use of fossil fuel emissions persons to the future of the United States will favor solar energy.
The sun's rays illuminate the Earth 40 minutes on the annual equivalent of the global energy consumption. In the United States, there are at least southwestern only 250,000 square miles of land suitable for building solar energy power generating facilities, over 4500, 2001 × 1015BTU acceptable sunlight radiation. Radiation of sunlight into electricity 2.5%, in 2006 the United States will meet all energy consumption.
The United States has put forward ambitious plans to make 2050 the United States to provide solar power for electricity and 69 per cent of its total energy (including transport) of 35 per cent. Expected sales to users of solar energy will be equivalent to the current cost of conventional electricity costs about 5 cents / KWh. If wind, biomass and geothermal energy has also been developed, to the 2100 renewable energy can provide 100 per cent of electricity and the United States 90 percent of its energy.

India Introduced Measures To Support Solar Power
India is currently implementing a plan, which seeks to those who use solar power plant and grid-connected power plants provide preferential policies.
New Energy and Energy Conversion officials said, the Department decided to implement the model plan, support in the construction and grid-connected solar power plant.
The scheme aims to develop and demonstrate the power grid interactive solar features, lower equipment costs and power generation costs.
Ministry officials said that the current solar power plant that the initial inputs and the costs of power generation, such as the decision of the Department with the power grid interactive power plant to provide incentive funding.
The Department will interact with the grid per kilowatt solar power provide a maximum of 270 cents. In the country's 11th five-year plan period, the demonstration project limited to 50,000 kilowatts of solar power plants.

BP Solar 100 Million Euros Building Solar Module Assembly Plant
Photovoltaic solar design, production and sales sectors of the European market leader in solar energy company BP in 2008 began in the second quarter of LaNavaII Puertollano Industrial Park building module assembly plant, the investment for 100 million euros.
The new plant will use modern technology manufacturing solar photovoltaic modules. The first stage production capacity will reach 300 MW / year, which means that the provision of energy can meet the 150,000 to 200,000 domestic demand, to reduce CO2 emissions equivalent to about 420,000 tons / year. The second phase of expansion will reach 500 MW.
BP Solar is a silicon and polysilicon technology to produce photovoltaic solar cells and modules. BP Solar companies in the industry with 30 years of experience, production factories in the United States, Spain, India, Australia and China.
