In this letter, graphene oxide (GO) and magnetic bead (MB) were incorporated into titanium dioxide (TiO2) photoelectrode by electrophoretic deposition and spin coating. The structure of TiO2 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 ( $\eta $ ) of DSSC achieve 4.63%. This improvement could be attributed to the high conductivity of GO and good dispersion of MB. [ABSTRACT FROM AUTHOR]
