Summary:

We have successfully demonstrated plasmonic enhancement of dye sensitized solar cells with up to 45 % increase in the cell power conversion efficiency by simply integrating a layer of island-like plasmonic gold nanoparticles with E-beam evaporation 5nm gold. Finite-difference-time-domain (FDTD) simulations are carried out to investigate the distribution of the plasmon-induced electric field in the 5nm island-like gold film. Furthermore, we believe the enhancement obtained in the dye sensitized cell is attributed to the plasmon-induced electric fields, which strongly increase the exciton generation and dissociations rate.
