  • Photovoltaic cell
    Patent number: 6933436
    Abstract: A photovoltaic cell is described, having a photoactive layer (4) made of two molecular components, namely an electron donor and an electron acceptor, particularly a conjugated polymer component and a fullerene component, and having two metallic electrodes (2, 5) provided on both sides of the photoactive layer (4). In order to provide advantageous construction ratios, it is suggested that an electrically insulating transition layer (6), having a thickness of at most 5 nm, be provided between at least one electrode (5) and the photoactive layer (4).
    Type: Grant
    Filed: April 27, 2001
    Date of Patent: August 23, 2005
    Assignee: Konarka Austria Forschungs und Entwicklungs GmbH

  • Photovoltaic cell
    Patent number: 6812399
    Abstract: A photovoltaic cell is described, having a photoactive layer (4) made of two molecular components, namely an electron donor and an electron acceptor, particularly a conjugated polymer component and a fullerene component, and having two metallic electrodes (2, 6) provided on both sides of the photoactive layer (4). In order to provide advantageous construction conditions, it is suggested that an intermediate layer (5) made of a conjugated polymer, which has doping corresponding to the electrode potential and, in regard to the electron energy, has a band gap between the valence band and the conduction band of at least 1.8 eV, be provided between the photoactive layer (4) and at least one electrode (2,6).
