Abstract

We fabricated layer-by-layer gold nanoparticles (Au NPs) onto an electrode as a Schottky barrier in a water-based dye-sensitized solar cell. The Maxwell-Garnett equation was used to fit the characteristics of the Au film. The short-circuit current for four layers of Au NPs in a water-based dye-sensitized solar cell (DSSC) ranges from 2.76 mA/cm2 to 5.96 mA/cm2, which is due to the Schottky barrier reducing the number of electrons going from the semiconductor back to either the dye or the electrolyte. The efficiency of photo-electric conversion for four layers of Au NPs in water-based DSSC can be enhanced from 0.26% up to 0.95%.
