Efficiency enhancement in dye-sensitized solar cells using the shape/size-dependent plasmonic nanocomposite photoanodes incorporating silver nanoplates

Abstract

In this work, we descibe the efficiency enhancement in dye-sensitized solar cell (DSSC) by using TiO2/silver nanoplate plasmonic nanocomposites photoanodes. The nanocomposites photoanodes with tunable plasmonic properties assembled from shape/size-selected silver (Ag) nanoplates were applied to enhance the light absorption for high-performance DSSCs. It was found that the localized surface plasmon resonance can be tuned over a range from 500 to 1000 nm, which is strongly dependent on the shape and size of Ag nanoplates and the refractive index of the surrounding dielectric. The effects of the size and shape of Ag nanoplates on the surface plasmonic resonance and the efficiency of DSSCs were evaluated experimentally. Furthermore, a three-dimensional finite element mothod was employed to investigate the localized surface plasmon resonance (LSPR) for the shape and size effect of Ag nanoplate.
