Australian engineering services company WorleyParsons launched a large-scale solar power plant construction projects, each cost about 1 billion Australian dollars, the generating capacity of 250,000 kilowatts, the first power plant to be completed within three years, will be the world's largest solar power Plant.
WorleyParsons estimates in Australia's first large-scale solar power generation plant of the cost per kilowatt for about 15 minutes Australia, the company's chief executive EcoNomics of Peter Meurs said that the future as new technologies come out, the cost of power generation plant can be Wang declined.
In the Australian government for the suppression of carbon emissions and set renewable energy targets and the introduction of the carbon emissions, WorleyParsons is working to in 2020 in Australia before the end of the construction of 34 solar power plants to meet the 40 percent renewable energy demand .
WorleyParsons solar power plant to not lose money, the pricing of carbon emissions will be substantially higher than the 10 Australian dollars per tonne, if set at 50 Australian dollars per tonne, while solar energy will be relatively cheap. Carbon emissions trading in the height of Europe, due in December this year of carbon emissions per tonne at current prices of about 26 euros (about 44 Australian dollars).

High-purity metallurgical grade silicon (UMG-Si) solar cell products into the market
CANADIAN SOLAR components that UMG e-Modules officially off the assembly line
In mid-June, CANADIAN SOLAR in Munich, Germany, the Intersolar exhibition, launched by a grand refined into metallurgical silicon solar grade silicon production of new components - and named for the e-Module. So that it will become the world's first successful metallurgical silicon (UMG-Si) solar grade silicon refined into commercial production companies.
The advantages of e-Modules
1. Cost advantages, UMG silicon (high-purity metallurgical grade silicon) is a selective purified silicon raw materials, as from the "Silicon ore - metallurgical silicon - High-purity silicon - monocrystalline silicon or polysilicon - silicon - the battery - Group Pieces - applications, "the battery industry chain in the third procedure, the high-grade metallurgical silicon processes to reduce the purification was not easy to introduce environmental problems caused by the chemicals, and reduce the cost of many. The current production of high-grade metallurgical silicon in the purchase price of approximately 60-70 dollars / KG, and the traditional polysilicon purchase price of up to 500 U.S. dollars / KG.
2. More environmental protection, production processes from the point of view, UMG silicon materials (high-purity metallurgical grade silicon) battery cleaner, producing less loss of energy in the process. Silicon, the basic pattern and its natural hybrid forms are harmless. It can be said, UMG silicon materials (high-purity metallurgical grade silicon) is the most economical on the market the most reliable of the most environmentally friendly photovoltaic material.
3. Battery the most important parameters - photoelectric conversion efficiency and the decay rate, UMG silicon materials (high-purity metallurgical grade silicon) for the conversion efficiency of the current 13-15 percent, and conversion efficiency than the traditional polysilicon little gap , And the cost savings as much as several times. Optoelectronic thin film solar cell conversion efficiency generally lower than 10%. In low-efficiency solar cells and thin film of crystalline silicon cells efficiently between, people naturally look forward to the third better choice.

Saflex PVB Solar Technology Services Industry
St. Louis / San Francisco joint news in North America held in the city of San Francisco in 2008 photovoltaic exhibition, Solutia's company announced that its Saflex photoelectric business to certain companies will provide packaging technology for the PVB (polyvinyl Butyraldehyde) dissection and technical services, these companies can produce the world's largest (5.7 square meters) of thin film solar cell components.
Solutia's Saflex company's business purpose is to optoelectronic thin film solar cell components for the market to provide packaging technology. When PVB interlayers were sealed in glass plate coated between, it can be included in the protection of electronic components. Independent tests prove that the use of packaging materials PVB as the solar component has the best reliability, which is why the PVB film solar cells as a packaging material selection of components key reason.
In the energy can be sent to the local or national power grids of large-scale solar cells under the strong market demand, the film solar cell components market each year to about 40 percent of the speed continue to grow. In 2007, Germany and Spain is the world's largest optoelectronic market, they occupy about 70 percent of the global market share.

Japan-Launched Ultra-Thin Crystalline Silicon Solar Cells, The Conversion Rate Of 12%
It is reported that Japan's Industrial Technology Research Institute of amorphous silicon and crystalline silicon heterojunction developed a 54 μ m thick solar cell modules, and has confirmed unit conversion efficiency of 12.1 percent. Japan's Industrial Technology Research Institute in July 08 to 28 ~ on the 29th Science Museum in Tokyo, Japan's future at the "fourth generation of solar energy research center will report the results" posted on the solar cells. Crystalline silicon solar batteries crystalline silicon wafer supply and prices, and other serious problems. And thin is the decisive factor in cost-cutting, research and development gradually active.
This time, production Research Institute crystalline silicon used in the formation of amorphous silicon thin film of the two-sided structure, significantly reduces the crystalline silicon layer thickness, and the thick only 54 μ m. "In the double-heterostructure products in the world's thinnest" (middle Research Institute). Such cells are easily bent by hand.
But after the cells are thin conversion efficiency decline. Thickness of 300 μ m, the conversion efficiency of 17.5 percent, while 54 μ m thick, fell to 12.1 percent conversion efficiency. This is by thinning, the wavelength greater than 900 μ m infrared use efficiency of the decline.

U.S. AMAT Display From India Ordered The Thin-Film Solar Cells
U.S. Applied Materials (AMAT) in solar cells show "PVJapan 2008" on display at the Indian Moser Baer Photo Voltaic the manufacturing floor size of 2.2 m × 2.6m film solar cell modules.
Moser Bare is the first production line using AMAT solar manufacturers. Moser Bare display modules, Construction show that AMAT production lines have been successfully launched. However, the module conversion efficiency, and other specific details were not released. AMAT Health Production lines are characterized by the floor size is capable of producing 2.2 m × 2.6m of large-size thin film of silicon solar cells.
