Zusammenfassung:In this letter, graphene oxide (GO) and magnetic bead (MB) were incorporated into titanium dioxide (TiO 2 ) photoelectrode by electrophoretic deposition and spin coating. The structure of TiO 2 photoelectrode was fabricated into a double-layer structure and the effects of GO and MB on the internal structure of dye-sensitized solar cells (DSSCs) were investigated. This letter indicated that GO and MB could enhance the photovoltaic performances of DSSC, which made the photovoltaic conversion efficiency (η) of DSSC achieve 4.63%. This improvement could be attributed to the high conductivity of GO and good dispersion of MB.
