Photovoltaics suffer from gross inefficiency, despite incremental improvements in their power producing capabilities. According to research by a team led by a University of Missouri professor, however, newly developed nantenna-equipped solar sheets can reap more than 90 percent of the sun’s bounty — which is more than double the efficiency of existing solar technologies. Apparently, some “special high-speed electrical circuitry” is the secret sauce behind the solar breakthrough. Of course, the flexible film is currently a flight of fancy and won’t be generating juice for the public anytime soon. The professor and his pals still need capital for commercialization, but they believe a product will be ready within five years. Take your time, guys, it’s not like global warming’s getting worse.
