Experimental results concerning the influence of plasmon effect from silver nanoparticles on the organic photovoltaic
device performance are presented. The metallic nanoparticles (NPs) are placed on top of ITO layer using a physical
vapor deposition technique. Poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) followed by an
interpenetrated poly(3-hexylthiophene): [6,6]-phenyl-C61-butyric acid methyl ester (P3HT:PCBM) blend layer are then
spin-coated. The aluminum electrode is finally evaporated on. Photovoltaic properties compared to devices without NPs
are shown. A spectrophotometric characterization is carried on. Moreover, a ToF-SIMS measurement is performed in
order to obtain the depth chemical profiles of solar cell containing such NPs. Silver NPs diffusion inside other layers of
the cell is investigated.
