The record efficiency was achieved in outdoor tests in Sydney, before being independently confirmed by the National Renewable Energy Laboratory (NREL) at their outdoor test facility in the United States.” DARPA pushes for 50% efficient photovoltaics to power soldiers' small tools spie.org/x8772.xml “Photovoltaic solar cells already provide the armed forces with portable power supplies. But with their present low efficiency, a 60W laptop recharger would require more than 0.37m2 of solar cells.” ____________________ DNews is dedicated to satisfying your curiosity and to bringing you mind-bending stories & perspectives you won't find anywhere else!
