American Scientists Believe That Solar Energy Is Expected To Become A Preferred Alternative Energy

American scientists Travis Bradford in the newly published "Solar Revolution," a book predicted that solar energy will be in the next 20 years to become the best effect, the price of the cheapest alternative sources of energy, prices will drop 50% in 10 years, after 20 years of decline 75% .

Bradford is the Massachusetts Institute of Sustainable Development Prometheus founder and president. He said that over the past 10 years has been the development of optoelectronic industries to obtain electricity through photovoltaic cells become economical and practical. Japan, Germany and the United States and other markets around the world, tens of thousands of households and enterprises are using photovoltaic technology.

He wrote that the construction of large wind power or geothermal power facilities now require supporting infrastructure, use of these two methods of generating at least half of funds should be used in the transmission and distribution. Using solar power, without electrical power grid will be able to transmit directly to end-users, the cost is only to tenants to install equipment costs. At present, the supply shortage of fine silicon solar panels limit production. Bradford believes that this situation will change after a few years. First, according to those large and reliable polysilicon manufacturing enterprises, as well as some in the manufacturing metallurgical grade silicon has extensive experience in new business to increase the output of the current situation to 2008, will double the supply of polysilicon. In addition, chips and solar battery maker is studying how to make more effective use of silicon.

He pointed out that some of the world's developing countries are often rich in solar energy resources, but the lack of use of solar energy resources. The future of solar energy prices drop significantly, a household will be able to spend 50 US dollars with a generating power of 30 watts of solar panels, used to recharge cell phones and listening to the radio and so on. In the United States, major residential construction companies are considering new construction using solar energy problems. California passed a new bill on the request of construction companies in 2012 to allow tenants choose to use solar power. Bradford believes that the future five years, the United States will become a solar energy use one of the fastest growing, will be more than Germany and Japan as the world's largest country in the use of solar energy.

United States Investment In India Photovoltaic Industry

India is increasing in the global market, the share of photovoltaic cell panels. Signet in California of the United States in solar energy company in late December 2007 that in the next 10 years will be 2 billion US dollars investment in India building three solar photovoltaic products manufacturing plant.

After three factories will be built with the annual output of 900 MW. India seeks to create the world's lowest cost of photovoltaic modules. Signet solar energy company also plans to establish R & D center in India.

India is an attractive local labor and low-cost manufacturing base. In addition, India's production of photovoltaic cell panels companies can enjoy tax breaks and subsidies. To this end, the market is expected to India's annual sales from the current 6 billion US dollars to a 2010 40 billion US dollars / year.

New photovoltaic manufacturing construction of the plant will accelerate India to enter the field of renewable energy. Currently India's renewable energy capacity of about 10 GW, the next 25 years will be increased to 80 GW.

South Africa Need To Vigorously Develop Solar Energy, Ease The Power Crisis

Professor at the University of South Africa, recently said that the country should be shifted to ease the country's solar power crisis.

The University of Johannesburg, said that solar energy technology development to become South Africa could become an economic solution to the power crisis in the way.

The new ultra-thin film materials used in the manufacture of solar panels can save more costs. The University believes that the new thin film PV material change to solar power will be completely changed way.

Previous silicon solar panels activities as PV materials, but the cost of imports expensive as the obstacles to the success of the law. The university said the new material (CIGS) that copper - indium - Gallium - even selenium can significantly reduce costs. From CIGS panels composed of very thin, flexible, and easy to bend, can replace old vitreous. And its efficiency is very high, supply stability, and can be used for family, it can be used in the wind farm.

Japanese Government Announced It Would Vigorously Popularize The Family Solar Power Generation

The Japanese Government has announced that the family should make great efforts to popularize solar power generation , to 2030, the family users from the current 400,000 to expand about 14 million, equivalent to the total number of households in Japan about 30%.

In order to make the average family can use solar power, the Japanese government decided to set up by Chinese and foreign experts of the international research institutions, specialized in low-cost solar panels of the new research and development and the inclusion in the annual budget of 20 billion yen.

Will be developed by the Government of Japan to improve energy efficiency than 1 ~ 2 times the new solar panels, and in 2030 their costs from the current 46 yen per kilowatt down to 7 yen. The objective is to in 2030 before residential solar power capacity (now 1.3 million kilowatts) expanded to 30 times.

Also Work The Night: Infrared Solar Panels Efficiency As High As 80%

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.
