Abstract

The N/TiO ₂ nanobelts anodes were prepared by sol and powder combination technology. Transmission electron microscope (TEM) and X-ray photoelectron spectroscopy (XPS) confirmed the structure of nanobelts and the modification of non-metallic element N. Electrochemical Impedance Spectroscopy (EIS) measurements showed that the R _ct2 corresponding to the TiO ₂/dye/electrolyte interface decreased 13.66 Ω. TiO ₂ in the form of belt was conducive to transmission of carriers produced by photoexcited dye. The modification of elements N led to a strong redshift to the visible region in the ultraviolet-visible spectra (UV-vis). Much more components of sunlight can be used. Therefore, the photoelectric conversion efficiency of dye-sensitized solar cell (DSSC) was improved.
