    Scientists develop ultra-thin solar cells

    The thin-film device, comprising electrodes on a plastic foil, is about 1.9 micrometers thick, a tenth the size of the thinnest solar cells currently available, the researchers said.

    "The total thickness of this device is less than a typical thread of spider silk," the researchers said in a report carried by online science journal Nature Communications.

    "Being ultra-thin means you don't feel its weight and it is elastic," said one of the researchers, Tsuyoshi Sekitani from the University of Tokyo.

    "You could attach the device to your clothes like a badge to collect electricity (from the sun)... Elderly people who might want to wear sensors to monitor their health would not need to carry around batteries," Sekitani told AFP.

    The research was done jointly by Martin Kaltenbrunner, Siegfried Bauer and other researchers from Johannes Kepler University of Austria as well as Sekitani and other contributors from University of Tokyo.

    Sekitani said it was possible to make the cells bigger.

    "Power generation by solar cells increases with their size. As this device is soft, it is less prone to damage by bending even if it gets bigger," he said.

    Sekitani said the team hoped to increase the rate at which the device converts sunlight into electricity and put it to practical use in around five years.

    Lighter, more flexible physically, and it the things it can be used for. Next, will be an large jump in efficiency. At that point it will be unreasonable not to have solar on your home.

    What's the point in posting this stuff? Hope and change? Look at all the qualifier words: "researchers said", "in a report" "you could" "might want" "was possible" "hoped to". We can't afford current solar junk that doesn't work so imagine if this stuff ever gets on the market how much it might cost.

    It's good news for 20-40 years down the line I suspect. Nothing that'll be worth much in the next 10-20 though.

    Still the major limiter is battery technology.

    More American innovation that is going to pull us up again.

    Your car could end up being made of collectors and batteries right into the outer design
