Abstract


  • Hierarchically structured aggregates, consisting of TiO2 nanoparticles were produced via one-step

    solvothermal syntheses with a mixed solvent system containing both acetic acid and ethanol. Two of

    the resulting structures, one ~700nm and the other ~300nm in diameter, were found to be comprised

    of 8.5nm and 10.5nm anatase crystals, and possess specifc surface areas of 138 and 106m2gāˆ’1

    respectively. These particles were incorporated into Dye-sensitized Solar Cells (DSCs) as high surface

    area scattering layers, along with a layer of a transparent material. Solar-to-electric conversion

    efciencies (PCE) of 9.1% and 8.2% were recorded using these aggregated particles as compared to

    those of commonly used large particles scattering layer 7.4%.
