Preparations of Titanium Composite Electrodes from Commercial Inorganic Pigment and Its Application to Light Scattering Layers on Dye-Sensitized Solar Cells
We synthesized three TiO2 composite (TiO2-Al2O3, TiO2-Nb2O5, and TiO2-ZrO2) electrodes by the hydrothermal method using titanium dioxide pigment and fabricated double layer dye-sensitized solar cells (DSSCs) using the TiO2 composites as the scattering layer. Due to their enhanced light harvesting capability, the performance of the double layer DSSCs with TiO2 composite top layer was better than that of the cells without the TiO2 composite top layer. A maximum power conversion efficiency of 6.68% was obtained for the double layer DSSCs with TiO2-Al2O3 composite layer under AM 1.5 illumination.
