Abstract

Polythiophene (PTh) films on carbon fibers (CFs) were applied to an electrode of a photo-rechargeable battery (PRB). The PRB is a battery which can convert photonic energy to electrochemical energy and in situ store it. PTh/CFs electrodes were prepared by electrochemical deposition at different temperatures, 0, 25 and 40 °C. The characteristics of photo-rechargeability were measured with the irradiation of xenon lamp. The surface flatness and the electrical resistivity of PTh/CFs were estimated using the experimental results of the electrochemical impedance. It was found that PTh/CFs prepared at 0 °C had high flatness and low resistivity.
