title: Highly efficient tandem polymer solar cells with a photovoltaic response in the visible light range.
abstract: Highly efficient polymer solar cells with a tandem structure are fabricated by using two excellent photovoltaic polymers and a highly transparent intermediate recombination layer. Power conversion -efficiencies over 10% can be realized with a photovoltaic response within 800 nm.
