ScienceDaily: A new material design tested in experiments at the Department of Energy's SLAC National Accelerator Laboratory could make low-cost solar panels far more efficient by greatly enhancing their ability to collect the sun's energy and release it as electricity. A team of University of California, Los Angeles, scientists found that by assembling the components of the panels to more closely resemble the natural systems plants use to tap the sun's energy, it may be possible to separate positive and negative...
