The United States will build solar power facilities in China
The first year in office as the first state visit to China on the U.S. president, Obama 18, ended a four-day visit to China. Throughout the “Chinese line” results, the two sides cooperate on climate issues statement on the popular foreign media attention.
In the 17, released more than 6,000 words long, “Sino-US Joint Statement”, only to climate change, energy and environmental issues involving more than 1,700 characters, the two sides adapter for laptoplaunched a series of specific measures to express confidence in co-operation. In the latest Associated Press reported that the two sides in the joint statement of the statement “encouraging”, with the Copenhagen climate summit approaching, the pressure on the parties to continue to increase, the two heads of state meeting for the General Assembly the convening of the first few weeks of consultation “to provide a new impetus.”
“Washington Post” entitled “US-China dialogue on the emission reduction targets,” the article said, “Sino-US Joint Statement” in the content shows that the two sides are expected to engage in further dialogue on the climate issue: oba Malaysian government is likely to climate summit in Copenhagen next month to raise emission reduction targets, while China will put forward their own proposals. “The New York Times” that the United States and China in clean energy, bright prospects for cooperation, the newspaper in its report also revealed that a U.S. company will soon build solar power facilities in China, while China has agreed to help in the United States Dirk SARS to build a wind farm in the state.
On trade issues, the two sides have expressed strong resistance to trade protectionism. The U.S. “Time magazine,” commented said the trade imbalance between the U.S. and the situation will continue to exist, but mainly because the one hand, U.S. companies in China share a number of products sold most or all “Made in China”, the United States trade relations between the United States has been deeply rooted in the economy, more importantly, with billions of people in China, it seems bound to impact on the economy than the United States, which means that on a breakthrough in US-China trade the deadlock is not easy.
The two sides on the exchange rate issue of concern has not made it clear. The United States, “McClatchy News,” pointed out that the exchange rate issue is not “black or white”, a large number of Chinese manufacturers and U.S. companies have established cooperative projects, or to get their orders, wholesale electronics a while the U.S. consumer has enjoyed more than a dozen years of “Made in China” products continue to decline in the price of the benefits, “these products from clothing to electrical appliances, shoes and hats.” (China Securities Journal Yang B)
Ministry of Finance will spend nearly 20 billion yuan to subsidize 642 megawatts of solar projects
Chinese Ministry of Finance issued a public notice that the Chinese government will in the next two years to invest in participation of nearly 200 billion yuan, the total installed power generation arrangement for the 642 megawatts of solar-scale demonstration projects.
Chinese Ministry of Finance, the Ministry of Science and Technology and the National Energy Administration jointly issued the notice. Installed capacity is greater than whole electronics the reference to a notice in July that 500 megawatts.
Chinese Ministry of Finance in July, said the solar power facilities under the project and associated transmission facilities investment costs of 50% will receive financial subsidies; an independent solar energy systems in remote areas the proportion of subsidies will be raised to 70%.
The Ministry of Finance said that each province have access to subsidies, the largest installed capacity of up to 20 megawatts, the Ministry of Finance also encourages local governments to demonstrate local financial support for solar energy projects. (Finet)
Novel optical fiber significantly reduce solar electricity prices
The researchers said recently that the use of specially designed optical fiber that allows solar energy to become cheaper.
Georgia Institute of Technology (Georgia Institute of Technology) Wang Lin (Zhong Lin Wang), led by Professor Group, created the shape of optical fiber around the bristles of the nano-wirehp Pavilion dv2000 battery ， hp Pavilion dv6000 battery ， hp Pavilion DV1000 battery bundles, an increase of the surface area of light interactions, improving the overall power generation efficiency of solar energy. According to the British BBC reported that the study published in the “Applied Chemistry” (Angewandte Chemie) magazine.
Because only the first optical fiber exposed to absorb light to generate electricity, so the roof will no longer need to install huge solar panels, replaced by a small solar collector, through the fiber-optic connections can be hidden in solar power generation equipment positions, such as between walls.
Professor Wang Zhonglin, said: “With this technology, we can create a fold-style, hidden type and movable photovoltaic power generation method.”
At present the most efficient and most familiar with solar cells based on silicon material preparation. Silicon absorbs sunlight, the release of Electronic and make migration to generate electricity. In recent years, dye-sensitized solar cells (dye-sensitised solar cells) to obtain a rapid development. This battery through the dye molecules absorb sunlight to release electrons. Dye-sensitized cells have the potential efficiency of its use is relatively low most of the cheap and durable material.
And Wang Zhong-Lin invented new ways to use telecommunications and other commonly used commercial optical fiber, the research team will be stripped the outer fiber in its surroundings to create zinc oxide nanowires bundle will dye molecules deposited on top of increased activity in response to an area, thereby helping to on improving the efficiency of the battery. Just as sunlight into the optical fiber ends, so the roof can install a small solar collectors, most of the power generation materials without the need to move to the roof, can be hidden in another location.
Wang Lin said: “The fiber can be the sun into the wall inside the nano-materials, solar energy into electricity. This is indeed a kind of three-dimensional solar cell.” Professor battery ec Wang said that in the future study, for the transformation of the surface of nanowires can be further improve the device efficiency.
Imperial College London (Imperial College London) solar cell researchers Saif • Haq (Saif Haque), said: “Professor Wang’s work pretty dry too, and this is really a way to improve utilization of sunlight a good way.”
