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.
