Popular Science Magazine has awarded Nanosolar’s PowerSheet solar cells the Innovation Of The Year award:

The company produces its PowerSheet solar cells with printing-press-style machines that set down a layer of solar-absorbing nano-ink onto metal sheets as thin as aluminum foil, so the panels can be made for about a tenth of what current panels cost and at a rate of several hundred feet per minute. With backing from Google’s founders and $20 million from the U.S. Department of Energy, Nanosolar’s first commercial cells rolled off the presses this year.

This could be big. With oil at what appears to be a new permanent level of $90-$100 a barrel, and solar coming down this much in price, it might finally catch on.
