中文摘要

This study investigated the applicability of TiO2/Au (or TiO2/Ag) composite particles,
which probably have the plasmon resonance effect, on FTO-glass substrate of the working electrode
of a DSSC. The dry particle coating technique was utilized to coat the surfaces of TiO2 particle with
nano-sized Au (or Ag) powder particles. A layer of TiO2/Au (or TiO2/Ag) composite particles was
deposited on the FTO-glass substrate of the working electrode, and it was then sintered in a
high-temperature furnace. The working electrode covered with a TiO2/Au (or TiO2/Ag) thin film was
kept immersed in a solution of N-719 (Ruthenium) dye for 12 h. Finally, the DSSC was assembled,
and the short-circuit photocurrent; the open-circuit photovoltage, and the power conversion efficiency
η of DSSC were measured using a home-made I-V measurement system. This study also examined
the effects of the mass ratio of TiO2 to Au (or Ag) and the duration of dry coating on the η of the
DSSC. If the duration of dry coating is adequate, the η of the DSSC with TiO2/Au (or TiO2/Ag)
composite particles increased with increase in the percentage of Au (or Ag) in the composite particles.
Most importantly, this study shows that the power conversion efficiency η of the DSSC with a film of
TiO2/Au (or TiO2/Ag) on the working electrode always exceeds that of the conventional DSSC due to
presence of the Schottky barrier, which is probably created in the TiO2/Au (or TiO2/Ag) composite
particle.
