Gallium arsenide nanowire solar cell with 7.7% efficiency
Norwegian scientists have developed a gallium arsenide (GaAs) nanowire solar cell that can be used as a top cell in a dual tandem cell with a bottom silicon cell. The device is claimed to be the most efficient single-junction GaAs nanowire solar cell grown on a silicon substrate so far.
