Plasmonic enhancement of dye- sensitized solar cells using Ag@PVP core-shell

We have demonstrated plasmonic effects on the performance of Dye-Sensitized Solar Cells (DSSCs) byincorporating metal-organic core-shell Ag-polyvinylpyrrolidone (Ag@PVP) nanoparticles (NPs). Experimental results show that Ag NPs capped by PVP, present chemical stability to iodide/tri-iodide electrolyte, which is one of the main factors when employing metal NPs in DSSCs. The influence of the Ag@PVP layer's thickness that was spin coated on TiO2 layer was also investigated. As a result, the power conversion efficiency (PCE) of DSSCs was increased from 4.28% to 6.19% upon incorporating Ag@PVP NPs by optimized coating parameters.to 6.19% upon incorporating Ag@PVP NPs by optimized coating parameters.
