It was found that UV irradiation can reduce the bulk and contact resistance of PEDOT:PSS films, improving the power conversion efficiency from (3.05 +/- 0.04)% to (3.50 +/- 0.03)% due to the lower device series resistance under an illumination of AM 1.5G, 100 mW/cm(2). The work function change after UV irradiation and negligible surface morphology change was noticed. (C) 2009 Elsevier B.V. All rights reserved.
