Water splitting dye-sensitized solar cells offer a possible solution to the future energy depletion by converting the energy from the solar spectrum to the chemical bond in Hydrogen molecules. However, the low quantum efficiency of water oxidation reaction at the photoanode limits the performance of the system. Studies have shown that the low electron injection yield and fast charge recombination are among the main efficiency loss mechanisms. Instead of conventional mesoporous TiO2 nanoparticle film for the photoanode, TiO2 nanowire array was used to study the impact of semiconductor morphology on electron diffusion and charge recombination. Kinetic parameters were measured by impedance and time-resolved spectroscopies. The results may provide future directions to improve the efficiency of water splitting dye cells.
