Fuel cell catalysts
The United States by the fuel cell catalyst nanoparticles atomic image
MIT engineers and has made environmentally friendly energy storage devices of the first nanoparticles single atom image.
Well-known platinum and cobalt nanoparticles mixed reaction to the fuel cell can play a catalytic role, and its reaction rate is simply four times platinum as a catalyst. However, no one knows the exact reason; This is because the nanoparticle surface atomic structure and chemical properties is poorly understood.
Now using aberration correction scanning transmission electron microscopy (aberration-corrected Scanning Transmission Electron Microscopy), can determine the atomic structure of the catalyst surface.
Q-Cells solar grade silicon for the first time on display unit to accelerate the development of solar cell manufacturers
Q-Cells AG of Germany in the International Society of solar cells and Exhibition "EU PVSEC", the first public using special silicon solar grade silicon solar cell manufacturing "Q6LEP3". Target is 2009 to 2010 for practical use, and the cell conversion efficiency of the same unit with the existing 16%.
With the use of the existing unit of raw materials compared to silicon, solar grade silicon solar cell to achieve a stable supply, and reduce costs. Therefore, as expected to ease the shortage of silicon raw materials flagship product, the practical use of concern.
This, Q-Cells, said, "use of the product, the battery can supply enough units to help companies grow faster solar cell modules," Therefore, "GROW FASTER (faster development)" the words together with the solar cells display.
To achieve the practical use of low purity solar grade silicon, can increase the cell conversion efficiency and to what extent is a major issue.
The display unit specification: Dimensions 156mm × 156mm (± 0.5mm), thick 180μm or 160μm (± 30μm). There are three wide and 1.5mm surface of the silver bus (Busbar).
