摘要：
Platinum (Pt) is widely used for counter electrode of dye-sensitized solar cell (DSSC). In order to improve the electrocatalytic ability of Pt counter electrode for DSSC, the graphene oxide (GO) and magnetic beads (MBs) were added into titanium dioxide (TiO2) colloid to modifying Pt-counter electrode. GO with high specific surface area could be used as the electrocatalyst for triiodide reduction in DSSC. Because of its high charge carrier mobility and photocatalytic activity, MBs could enhance the photovoltaic properties of DSSC. Moreover, the effects of Pt counter electrode modified by GO and MBs for DSSC were investigated by X-ray diffraction, solar simulator, and electrochemical impedance spectroscopy. Compared with the photovoltaic conversion efficiency (PCE) of 2.31% of the conventional DSSC using Pt counter electrode, the catalyst properties of Pt counter electrode with GO and MBs had been improved and the PCE achieved 3.62%.
