Cu2S counter electrodes were prepared from the metal chalcogenide complex precursor using a novel method. A porous TiO2 nanoparticle film and TiO2 nanorod array photoanode were also fabricated. The corresponding CdS/CdSe-sensitized solar cel s with the Cu2S counter electrode were assembled and their photovoltaic performances were studied. The catalytic performance of the Cu2S counter electrodes was investigated using electrochemical impedance spectroscopy. Compared with a platinum counter electrode, the Cu2S one exhibited higher catalytic activity and better photovoltaic performance in quantum dot-sensitized solar cel s.
