In order to improve the mobility of photoexcited carriers the nanofibers (NFs) of Sn-doped In₂O₃ (ITO) with small resistance prepared by electrospinning method were applied in the TiO₂ nanoporous layer of dye-sensitized solar cell (DSC), as a current collector. In this study, to reduce the leak current from the surface of ITO-NFs, ITO-NFs were coated with TiO₂ dense layer on the surface by dip-coating method with TiCl₄ solution, and the change of photovoltaic properties of DSC with dip-coating time was examined by I-V measurements etc.
