Abstract

There are two factors on the efficiency of dye-sensitized solar cell (DSSC): one is the amount of dye adsorbed, and the other is contact resistance. In this study, TiO₂ nanoparticles (nano-TiO₂, about 20 nm particle size) were infiltrated between mesoporous TiO₂ (meso-TiO₂) particles with about 300 nm particle sizes, in order to reduce the contact resistance of TiO₂ electrodes. The infiltrated nano-TiO₂ can facilitate electron transfer between meso-TiO ₂ particles by filling the empty volume of DSSC electrodes. As a result, the TiO₂ electrode containing 65 wt% of meso-TiO₂ and 35 wt% of nano-TiO₂ exhibited the highest performance of DSSC.
