    Abstract

    Homopolymer photovoltaic devices based on thin films of polybithiophene, prepared by direct electrodeposition. onto transparent fluorine-doped tin oxide electrodes followed by evaporation of an aluminium electrode to complete the device, were reported by Leguenza et al. [J. Solid State Electrochem. 11 (2007) 577.] to exhibit very high open-circuit voltages (V-oc) of up to 2 V at a very low light intensity of 6.6 W m(-2). In this letter, we report our attempts to reproduce the results. We achieved V-oc's 200 W m(-2)) and at high current densities (> 1 mA cm(-2)) which has not been achieved yet. (C) 2007 Elsevier B.V.
