Periodic arrangement of mono-dispersed gold nanoparticles for high performance polymeric solar cells

We report on 80 nm diameter mono-dispersed gold nanoparticles ordered along lines by means of soft lithographic method on PEDOT:PSS layers. Silicon based mold engraved with Bragg gratings were employed to accomplish the periodic nanoparticles arrangement on large area surface. The results are promising for an increase of the power conversion efficiency in polymeric solar cells.
