Gallery: BREAKING: Solar Power Breakthrough Could Render Photovoltaic C...

With efficiencies equal to current commercial-grade solar panels, the new solar tech could lead to more affordable home-based solar arrays that integrate more seamlessly into your home--maybe even directly into your windows.
 

Researchers at the University of Michigan have made a discovery about the behavior of light that could change solar technology forever. Stephen Rand, a professor in the departments of Electrical Engineering and Computer Science, Physics and Applied Physics and William Fisher, a doctoral student in applied physics, discovered that light, when traveling at the right intensity through a material such as glass that does not conduct electricity, can create magnetic fields that are 100 million times stronger than previously thought possible. In these conditions, the resulting magnetic field is strong enough to rival a strong electric effect. The result is an “optical battery, which could lead to “a new kind of solar cell without semiconductors and without absorption to produce charge separation”, according to Rand.

Rand revealed the research in a paper published in the Journal of Applied Physics. Instead of requiring semiconductor processing, the new technique would only require “lenses to focus the light and a fiber to guide it,” according to Fisher. “Glass works for both. It’s already made in bulk, and it doesn’t require as much processing. Transparent ceramics might be even better.” Rand and Fisher predict that they could achieve efficiency with this new technology that is equivalent to today’s commercial-grade solar cells.

With efficiencies equal to current commercial-grade panels, the new solar tech could lead to more affordable home-based arrays that integrate more seamlessly into your home–maybe even directly into your windows?

    Lets not let this energy breakthrough get bought by Big Energy and buried like so many of the others through history. The time is short to allow this energy to spread over the planet.

    Amazing how in the dark some people are. Maybe its the media they are tuned to??

    Some facts:

    U-M scientists and engineers have been awarded more than 500 federal stimulus-package research grants to date, totaling $301.1 million.

    …The solar project is the U-M’s largest stimulus award to date.

    OK, very good! Now… HOW much and WHEN?

    GO BIG BLUE!!

    Private industry often provides research funds to universities to carry out the research. Not every company is set up with the kind of labs that universities already have.

    Gosh. Some people have difficult seeing beyond the horizon of their own ideology.

    Free-market: if it works, quite helpful. But not a standalone device, except for fantasists.

    Did you forget to read the bit above about this breakthrough coming from a post-doc at U Michigan?

    Um, yeah. It’s like that y’all. Public sector investments in research always drive private sector gains at this scale. Because these champions of free-marketeering would never ‘invest’ in the basic science required to discovered weird stuff like this. Of course they want to /exploit/ it. But discover it? Meh. Leave that to the geeks. Etc.

    Gah. How many times must this be revealed/repeated? Even medical research works this way; building on basic science done in unis.

    Great!

    Careful there, Lazy, that kind of free market and competition talk might get you kicked out of these parts.

    And to think we we’re supposed to buy all those solar panels and all those factories and other stuff that was built on stimulus money that now will is obselete or will under perform. Let the free market loose to develop this stuff on their own.

    sounds good, hope they can get it marketed quickly

  11. umar butt April 15, 2011 at 1:37 am

    yes we need new advanced and cheap solar energy solutions specially for people living in third world countries where electricity has not reached yet.

  12. caeman April 14, 2011 at 2:48 pm

    Even if it isn’t as efficient, removing the need for rare earth elements in the voltaic electronics is a big step forward for solar electric. Glass is super cheap and super plentiful. We have entire deserts of the stuff!
