Abstract
TiO2 spindles with high crystallinity were synthesised by a two-step solvothermal reaction with the aid of diethylamine. Compared with Degussa P25, the dye sensitised solar cell (DSSC) based on a TiO2 spindles photoanode demonstrated superior characteristics including higher affinity to N719 dye, higher light scattering effect than P25, better conductance and longer recombination lifetime. Photovoltaic measurement indicated that the TiO2 spindles-based DSSC possesses higher short-circuit current density (Jsc) and open-circuit voltage (Voc), hence, a 29% higher overall photovoltaic performance (%) than that of P25 was achieved.
