  • Tandem junction photovoltaic cell
    Patent number: 9741882
    Abstract: A tandem junction photovoltaic cell has a first p-n junction with a first energy band gap, and a second p-n junction with a second energy band gap less than the first energy band gap. The junctions are separated by a quantum tunneling junction. The first p-n junction captures higher energy photons and allows lower energy photons to pass through and be captured by the second p-n junction. Quantum dots positioned within the first p-n junction promote quantum tunneling of charge carriers to increase the current generated by the first p-n junction and match the current of the second p-n junction for greater efficiency.
