摘要：TiO2 Monodisperse microspheres (MMS) assembled by nanoporous spindles were successfully synthesized a facile hydrothermal method using P25 as precursor. The anatase TiO2 MMS possesses high surface area of 88.7 m(2) g(-1) with uniform diameter of similar to 350 nm. The photovoltaic performance of MMS based photoanode was investigated in the dye-sensitized solar cell. Due to high dye loading amount, good light harvesting and suppressed carried recombination, the device based on MMS exhibited an excellent short-circuit current density of 16.15 mA cm(-2) and high open-circuit voltage of 740 mV, which leads to the optimal power conversion efficiency of 8.43% indicating a similar to 40% enhancement than the commercial P25 based device (5.99%).
