Shrunken Cells – New Kind of Thin Film PV

When it comes to solar cells, it helps to be flexible – literally.  Thin, flexible cells exist although they usually fall short in terms of how efficient they are, how much they cost, etc.  Researchers from the University of best price generic viagra Illinois at Urbana-Champaign, however, have recently developed a cell that is both flexible and buy cheap online viagra powerful.

John Rogers, a materials science professor who led the multi-discipline research, has come up with a process of slicing conventional silicon into thin pieces that can be imprinted onto a flexible surface.  The result: efficient silicon-based solar cells flexible enough to wrap around a pencil and so transparent it can be used to tint building or car windows. The silicon cells are just one-tenth the only best offers dose cialis thickness of conventional cells and, according to Technology Review, they have about an efficiency of 12% - not too shabby considering that the best cells on www.velikibrat.us the market get 20% efficiency.  The findings were reported in the journal Nature Materials this week.

“We can make it thin enough that we can put it on plastic to buy cialis pill make a rollable system,” said Professor Rogers in an interview with Reuters. “It opens up spaces on the fronts of buildings as opportunities for solar energy.”  Other applications for the thin, rollable solar cells include powering the AC or GPS in a car.

Essentially, Professor Rogers’ cells use the same technology found in standard large, bulky PV units; it is the dosage levitra small size that accounts for their improved properties.  They can therefore be manufactured using the same monocrystalline silicon available for their macro-sized cousins.  Professor Rogers’ research has been licensed to a Durham, North Carolina company called Semprius Inc.

Introducing the solar powered pencil!
written by Francis, October 07, 2008
I've always been intrested in using solar energy as an alternative to fossil fuels. I'm glad that new ideas for creating solar cells have come about..I can only hope it doesn't come with too high of a price tag. Solar energy power plants produce an huge about of electricity....however, they are expensive to build. I hope they can find cheaper, more efficent ways to use all forms of http://revistaneon.net/cialis-professional-no-prescription alternative energy.
