摘要: A Sn-doped In₂O₃ (ITO) nanowire photoelectrode was produced using a simple metal evaporation method at low synthesis temperature (＜540℃). The electrodes have large surface area compared with that of flat ITO thin film, and show electrical resistivity 5.6×10 ?3 Ω㎝ room temperature. In order to apply nanowires the photoelectrodes dye-sensitized solar cell (DSSC), those surfaces were modified by TiO₂ nanoparticles chemical bath deposition (CBD) method. conversion efficiency fabricated TiO₂/ITO nanostructure-based DSSC obtained 1.4%, which increased value factor 6 than one without photoelectrode. This result is attributed superior property photoelectrode, as well structural advantages, including short diffusion length photo-induced electrons, TiO2/ITO DSSC.
