Flexible Nanoantennas Put Us On The Road To Affordable Solar Power

Researchers at the U.S. Department of Energy's Idaho National Laboratory say they have devised an inexpensive way to produce plastic sheets containing billions of nanoantennas that collect heat energy generated by the sun and other sources. They say this technology is the first step toward a solar energy collector that could be mass-produced on flexible materials. Traditional solar cells rely on a chemical reaction that only works for up to 20 percent of the visible light they collect. Scientists have developed more complex solar cells with higher efficiency, but these models are too expensive for widespread use. Read More...
