Abstract
Zirconia (ZrO2) nanofibers added mesoporous titania (TiO2) photoelectrode has been synthesized for dye-sensitized solar cells to enhance the efficiency of cell. The ZrO2 nanofibers had reduced the resistance of the photoelectrode as well as enhancement of the absorption spectra in the ultraviolet (UV), visible, and near infrared (IR) region. The internal resistance of the photoelectrode is one of the important factor to affects the power conversion efficiency directly. The ZrO2 nanofibers provide the more photon harvest and optimal electron pathway. Finally, about 200% increases in conversion efficiency has been achieved.
