Abstract
The super-porous TiO2 film is prepared with the block copolymer Pluronic F-127 as porous template. Comparing with the commonly used meso-porous TiO2 film prepared with Polyethylene glycol 20,000 as pore former, the super-porous TiO2 film shows higher photovoltaic performance when integrated it into polymer gel electrolyte based quasi-solid-state dye-sensitized solar cell (QS-DSSC). The enhanced dye adsorption, light scattering properties of the super-porous TiO2 film improve the utilization efficiency of sun light to be converted to electricity. Moreover, the special microstructures of the super-porous TiO2 film also makes for the deep penetration of polymer gel electrolyte into the dye-coated TiO2 film, which is the prerequisite for highly photovoltaic performance of polymer gel electrolyte-based dye-sensitized solar cell. So it presents a feasible way to enhance the photovoltaic performance of QS-DSSC.
