Abstract
In this study, we introduced gold nanoparticles NPs into the photoelectrodes of dye-sensitized solar cells (DSSCs) to study the effect of surface plasmon resonance from gold nanoparticles on the cells. Two different approaches were examined. First, a TiO$_2$-based composite photoelectrode with Au NPs and luminescent ZrO$_2$:Er$^{3+}$ phosphor NPs was used to improve the overall solar light harvesting through both the up- and the down-conversion luminescence properties of the ZrO$_2$:Er$^{3+}$ phosphor particles and the plasmonic effect of the gold nanoparticles. In the second method, composite TiO$_2$ nanofibers integrated with Au NPs were used as a light-harvesting layer in a photoelectrode to increase the conversion efficiency of the DSSCs. In a typical preparation process, the photoelectrodes with and without gold nanoparticles were prepared to compare their efficiencies. The results show that the efficiency of the DSSCs was decreased when gold nanoparticles were added into the photoelectrodes.
