    Five-junction photovoltaic cell has 44.5% efficiency

    Scientists at George Washington University and the U.S. Naval Research Laboratory (both in Washington, DC), Sotera Defense Solutions (Annapolis Junction, MD), Semprius (Durham, NC), and the University of Illinois Urbana-Champaign have designed and constructed a prototype for a new solar cell that has five semiconductor junctions — three in a gallium arsenide (GaAs)-based section and two in a gallium antimonide (GaSb) section.1

    The two overlapping types of photovoltaic cell each capture a different portion of the solar spectrum, allowing conversion of direct sunlight to electricity with 44.5% efficiency, giving it the potential to become the most efficient solar cell in the world. By comparison, the ubiquitous silicon solar cell converts only a quarter of the available energy into electricity.
