Electron Transport in Dye-Sensitized Solar Cells Based on ZnO Nanotubes: Evidence for Highly Efficient Charge Collection and Exceptionally Rapid Dynamics
Martinson, Alex B. F.; Góes, Márcio Sousa; Fabregat-Santiago, Francisco; Bisquert, Juan; Pellin, Michael J.; Hupp, Joseph T. American Chemical Society (2009)Dye-sensitized solar cells based on ordered arrays of polycrystalline ZnO nanotubes, 64 μm in length, are shown to exhibit efficient electron collection over the entire photoanode array length. Electrochemical impedance ... -
Impedance Spectroscopy Analysis of the Effect of TiO2 Blocking Layers on the Efficiency of Dye Sensitized Solar Cells
Góes, Márcio Sousa; Joanni, Ednan; Muniz, Elaine C.; Savu, Raluca; Habeck, Thomas R.; Bueno, Paulo R.; Fabregat-Santiago, Francisco American Chemical Society (2012)The introduction of a dense TiO2 layer between the mesoporous TiO2 network and the charge collector in dye-sensitized solar cell anodes has been claimed to improve the performance of solar cell devices. Two mechanisms have ... -
Surface Passivation of Nanoporous TiO2 via Atomic Layer Deposition of ZrO2 for Solid-State Dye-Sensitized Solar Cell Applications
Li, Tina C.; Góes, Márcio Sousa; Fabregat-Santiago, Francisco; Bisquert, Juan; Bueno, Paulo R.; Prasittichai, Chaiya; Hupp, Joseph T.; Marks, Tobin J. American Chemical Society (2009)We report here the utilization of atomic layer deposition to passivate surface trap states in mesoporous TiO2 nanoparticles for solid-state dye-sensitized solar cells based on 2,2′,7,7′-tetrakis(N,N-di-p-methoxyphenylami ...
