    By harvesting waste heat, researchers from the US Department of Energy’s National Renewable Energy Laboratory (NREL) have for the first time built a solar cell with an external quantum efficiency over 100 percent.

    A cell's external quantum efficiency is the number of electrons flowing per second in its external circuit, divided by the number of photons per second entering it, and is different at different wavelengths.

    The best result for the NREL solar cell was 114 percent. it means, says the team, that solar energy has a competitive future, making it possibly cheaper than energy from fossil or nuclear fuels.

    The team used a process called Multiple Exciton Generation (MEG), whereby a single absorbed photon of appropriately high energy can produce more than one electron-hole pair per absorbed photon.

    Bring it on.

    Back out 11 million barrels per day of molecularly complex, hydrocarbon rich liquids.

    Sell us on this shit just like we were sold on ethanol.

    Give it your best shot.
    Oh wait- you just did. :lol:

    Solar could be cheaper than coal and oil someday, boys, so close the mines and cap the wells now!

    I could be wrong, but aren't you being a tad presumptuous?

    presumptuous n. : taking liberties

    And this is supposed to be ready for mass production ... when?

    How China dominates solar power

    Huge loans from the Chinese Development Bank are helping Chinese solar companies push American solar firms out of the market

      Armed with tens of billions in loans from the Chinese government, Chinese solar companies have scaled at a rate unthinkable only a few years ago. At the end of this year, there will likely be 50,000 megawatts (MW) of manufacturing capacity in place around the world, with much of that new capacity being developed in China and other Asian countries. (In the year 2000, there were only 100 MW of production capacity worldwide.)
      In four years, the solar manufacturing sector shifted from being led by a geographically dispersed number of companies to one dominated by Chinese companies. In 2006, there were two companies from China in the list of top ten cell producers. In 2010, there were six, according to Bloomberg New Energy Finance. There are currently only two non-Asian manufacturers in the top ten, and those companies -- First Solar and Q-Cells -- have shifted a lot of their production to Asia.
      So what happened? How did the Chinese come to completely dominate the solar industry in such a short period of time?
      Bryan Ashley, the Chief Marketing Officer for Suniva, an American company that produces high-efficiency solar cells in Georgia, doesn't mince words.
      "The Chinese strategy is very clear. They are engaging in predatory financing and they're trying to drive everybody else out of the market. When you've got free money you can out-dump everybody below cost," Ashley said in an interview with Climate Progress.
      That "free money" Ashley refers to is the cheap debt provided by the

    Just think if we had listened to Carter all those years ago?

    we would be making a killing in solar.

    Instead the big energy got to keep selling more oil and kept certain families VERY wealthy even if we had to fight wars for their benifit.

    You have been had you clowns and your response to being had is "please have us some more".

    Sheesh... TM, you post as though it's the end of the world... really... it's not too late to make some adjustments.
