Enhancement of power conversion efficiency has been a persistent objective for dye-sensitized solar cell (DSSC). We represent here the feasibility of incorporating graphene into mesoscopic TiO2 with an aim of reducing electron loss within an anode. Results indicate that the short-circuit current density has been markedly enhanced due to the facile transfer of photogenerated electrons along graphene network from conduction band of TiO2 nanocrystallites. An optimal power conversion efficiency of 7.56% is recorded from the DSSC employing 0.03 wt% graphene integrated TiO2 in comparison with 5.21% for pristine TiO2 based solar cell.
