Abstract:

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 cells 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 cells.
