    Electrochemically deposited poly(3-methylthiophene) performance in single layer photovoltaic devices

    Photovoltaic devices based on electrochemically synthesized poly(3-methylthiophene) PMeT were constructed and characterized. The charge mobility for positive carriers of this polymer is quite high, 4 x 10-4 cm2/V...

    Considerations about the electrochemical estimation of the ionization potential of conducting polymers

    The energy gap and ionization potential of some conducting polymers such as polypyrrole and the polythiophene derivatives, poly(3-methylthiophene) and poly(3-hexylthiophene), are estimated using optical and e...

    Polypyrrole-poly(3-methylthiophene) bilayer films electrochemically deposited onto tin oxide

    We report the electrochemical successive deposition of layers of polypyrrole and poly(3-methylthiophene), forming conjugated polymer heterostructures onto a tin oxide-covered glass substrate. The polymer bila...

    Photovoltaic devices based on electrodeposited poly(3-methylthiophene) with tin oxide as the transparent electrode

    We report on the use of electrodeposited poly(3-methylthiophene) (PMeT) in photovoltaic devices. Photocurrent measurements in devices with PMeT as the active conjugated polymer layer were carried out showing ...

    Electrical characterization of poly(3-methylthiophene) electrosynthesized onto a tin-oxide substrate

    We have investigated poly(3-methylthiophene) (PMeT) thin films electrochemically synthesized directly onto a tin-oxide (TO) electrode. We find that the PMeT film thickness depends linearly on the charge densi...

    Electrosynthesis and characterization of poly(3-methylthiophene) on different substrates

     We report on the study of the electropolymerization of 3-methylthiophene onto Pt, p-Si and indium-tin oxide deposited on polyester using quartz crystal microgravimetry, electrochemical and spectroelectrochemi...
