Enhanced photocurrent properties of Dye/Au-loaded TiO<inf>2</inf>films by grating-coupled surface plasmon excitation
We report enhanced photocurrent properties of dye/Auloaded titanium dioxide (TiO 2 ) films on Au gratings. Au-loaded TiO 2 nanopowders were first synthesized by a modified sol-gel method and then prepared by the impregnation method. We also fabricated dye-sensitized solar cells, which were composed...

| Summary: | We report enhanced photocurrent properties of dye/Auloaded titanium dioxide (TiO 2 ) films on Au gratings. Au-loaded TiO 2 nanopowders were first synthesized by a modified sol-gel method and then prepared by the impregnation method. We also fabricated dye-sensitized solar cells, which were composed of Au grating/Au-TiO 2 /TMPyP-SCC LbL (20 bilayers)/ electrolyte/ITO substrates. Short-circuit photo-current measurements showed that Au-loaded TiO 2 with grating-coupled surface plasmon excitation can enhance the short-circuit photocurrentof the fabricated cells.
