Researchers in Germany report a new world record for the conversion of sunlight into electricity using a new solar cell structure with four solar subcells. A new record efficiency of 44.7% was measured at a concentration of 297 suns, indicating that 44.7% of the solar spectrum's energy, from ultraviolet through to the infrared, is converted into electrical energy. The achievement is being hailed as a major step towards reducing the costs of solar electricity.
