N2 - The most efficient dye-sensitized solar cells (DSCs) are not limited by electron diffusion dynamics, but the most desirable DSCs do benefit from more rapid electron collection. Photoanodes based on ZnO nanotubes fabricated by atomic layer deposition and incorporated into completed devices were studied by electrochemical impedance spectroscopy. Evidence is presented for an electron diffusion coefficient three orders of magnitude larger than any previously reported for a DSC photoanode to date. The first steps toward leveraging the improved photoanode properties are discussed.
