Abstract

TiO ₂ film for use as dye-sensitized solar cell was prepared using the TiO ₂ colloidal sols (unpeptized sol and peptized sol). The optical properties and photocurrent-voltage characteristics of the resultant films were investigated. The optical transmittance of TiO ₂ thin film prepared from the peptized colloidal sol was over 90%, while that of TiO ₂ film from the unpeptized sol was under 80%. The TiO ₂ photoelectrode prepared from the peptized colloidal sol showed low photoelectric conversion efficiency (η), 1.30%, whereas the efficiency of photoelectrode from the unpeptized sol was 2.21%. The high optical transmittance and low conversion efficiency of TiO ₂ film from the peptized sol are discussed in terms of dense microstructure due to the drying nature of well-dispersed colloidal sol.
