Abstract
Dye-sensitized solar cells based on highly porous nanocrystalline TiO 2 films have drawn considerable attention due to their high conversion efficiency and low production cost. TiO 2 nanocrystalline electrodes have been investigated extensively as a key material. In this study, we discuss dye-sensitized solar cells based on macroporous TiO 2 films using a highly-dispersed aqueous solution of TiO 2 nanoparticles and polymeric particles. After drying this solution on the conducting glass substrate, the sacrificial polymer particles were removed selectively by thermal sintering at high temperatures over 400 °C or chemical treatment at the low temperature of 150 °C. This method provides the flexible control of TiO 2 fractions or pore size or fabrication temperature. Also highly-dispersed TiO 2 particles with a high crystallinity would provide a promising solution on low-temperature process for flexible DSSCs.
