"increased the levels of energy absorbed by wafer-thin photovoltaic panels by 25%. Their solar panels, just one micrometer thick (1μm), convert light into electricity more efficiently... absorption rates of 26.3 mA/cm2, a 25% increase on the previous record of 19.72 mA/cm2...They secured an efficiency of 21% but anticipate that further improvements will push the figure higher, resulting in efficiencies that are significantly better"
