AB  - Titanium dioxide (TiO(2)) photoelectrodes with micro/nano hierarchical branched 
      inner channels have been prepared by an electrohydrodynamic (EHD) technique and 
      assembled to form dye-sensitized solar cells (DSSCs). Excellent penetration of 
      ionic-liquid electrolytes and enhanced light harvesting in the longer wavelength 
      region are realized within the composite-structure electrode, thus a better fill 
      factor (ff) of 75.3 % and higher conversion efficiency (eta) of 7.1 % are 
      obtained for viscous ionic-liquid electrolytes compared to pure nanostructured 
      films. Hierarchical branched channels in the photoanodes can efficiently improve 
      the transport properties of redox-active species in viscous electrolytes, which 
      is demonstrated by electrical impedance spectroscopy (EIS). The incident 
      monochromatic photon-to-electron conversion efficiency (IPCE) shows that enhanced 
      light scattering in the composite film is of benefit for light harvesting and 
      thus for solar energy conversion efficiency.
