| 英文摘要 | Titanium dioxide (TiO2) photoelectrodes with micro/nano heirarchical 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 wave-length 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 branced channels in the photoanodes can efficiently improve the transport properties of redox-active species in viscous electrolytes, which is demonstrated by electric impedance spectroscopy (EIS). The incident monochromatic photon-to-electron conversion efficiency (IPCE) shows that enhanced light scaterring in the composite film is of benefit for light harvesting and thus for solar energy conversion efficiency. |
