title: The Effect of UV-Ozone Treatment on the Performance of Plasmonic Organic Solar Cells.
abstract: Silver nanoparticles (Ag NPs) solution was spin-coated on indium-tin oxide (ITO) glass substrates prior to spin-coating poly(3,4-ethylenedioxythiophene):poly(styrene- sulfonate) (
  PSS) for the plasmonic solar cells. The sequence of spin-coating of Ag and UV-ozone treatment resulted in different device performance. For devices in which Ag NPs solution was spin-coated on ITO substrates before UV-ozone treatment, power conversion efficiency increased from 3.4% to 3.7%, while the power conversion efficiency decreased if Ag NPs solution was spin-coated after UV-ozone treatment. In both cases, the short-circuit current density increased, and the open-circuit voltage remained relatively constant. The variation of power conversion efficiency mainly depended on the changing of the fill factor, which is related to film morphology of the devices. AFM measurements of
  PSS films were taken to study the influence of film morphology on device performance.
