  • High efficiency tandem solar cells on silicon substrates using ultra thin germanium buffer layers
    Publication number: 20050081910
    Abstract: A system is disclosed for providing electrical power responsive to solar energy. The system includes a Si cell, an AlGaAs cell, and a Ge cell. The Si cell is for providing electrical power responsive to solar energy within a first frequency range. The AlGaAs cell is coupled to a first side of the Si cell, and is for providing electrical power responsive to solar energy within a second frequency range. The Ge cell is coupled to a second side of the Si cell, and the Ge cell provides electrical power responsive to solar energy within a third frequency range.
