Dye-Sensitized Solar Cells Assembled with Modified Photoanode and Carbon Nanotubes as Counter Electrode

Abstract:

A dye-sensitized TiO₂ thin film photoanode and carbon-based counter elctrode were fabricated on the FTO substrate with doctor-blade method. And we have coated the ZnO nanoparticles successfully on the TiO₂ photoanode through a simple dipping treatment. The photoelectric performance of the assembled cells was investigated by absorption spectra and current-voltage characteristics (I-V curves). Results show that the absorbance of ZnO/TiO₂ composite photoanode increases 5.4% compared to pure TiO₂ photoanode. The optimal photoelectronic property can be reached when dipping time is 2h in Zn (CH₃COO)₂ solution. And at this point, the photoelectric conversion efficiency increases up to 50%. The enhancement mechanism has been discussed in detail.
