A new world record is making the future of solar energy look pretty bright. Researchers in Australia recently developed a solar energy system that can convert more than 40 percent of the sunlight that hits it into electricity the highest efficiency ever reported for a commercially available photovoltaic system.
The technology first achieved the record-breaking efficiency in outdoor tests in Sydney, Australia, and later at an outdoor test facility operated by the National Renewable Energy Laboratory (NREL) in Golden, Colorado, the primary lab for renewable energy and energy efficiency research in the United States
Martin Green, a professor at the University of New South Wales (UNSW) and director of the Australian Centre for Advanced Photovoltaics, led the research group that built the new energy system. This wasn’t the first time Green and his team broke a world record for solar energy efficiency. [Top 10 Craziest Environmental Ideas]
