Electrode structure, method and applications
Abstract:
An organic photovoltaic cell structure and a method for fabricating the organic photovoltaic cell structure are each predicated upon an organic photovoltaic material layer located and formed interposed between an anode and a cathode. The organic photovoltaic cell structure and the method for fabricating the organic photovoltaic cell structure also include for the anode a nickel and indium doped tin oxide material layer (Ni-ITO) that has a nickel doping sufficient to provide a work function of the nickel and indium doped tin oxide material layer (Ni-ITO) anode preferably no more positive than about −5.0 eV. Such a composition of the nickel and indium doped tin oxide material layer (Ni-ITO) anode provides for a superior bandgap matching to a B3HT p-type donor component within a B3HT:BPCM BHJ organic photovoltaic material layer while also providing a greater bandgap separation of an aluminum material layer (Al) cathode to provide for enhanced electric field and charge carrier transport and collection capabilities of an organic photovoltaic cell device that derives from the organic photovoltaic cell structure.
