Solar Breakthrough? As Soon As We Defy the Laws of Physics

Scientists at Lawrence Berkeley National Laboratory say they've developed a new manufacturing process that allows them to build a material that could goose up the power output of solar cells, reaching efficiencies of 45% compared to the 25% to 39% currently possible. It's done using a tricky process of injecting… »10/10/06 12:49pm10/10/06 12:49pm
