Solution-processed metallic conducting polymer films as transparent electrode of optoelectronic devices

Abstract

The conductivity of PEDOT:PSS films was significantly enhanced from 0.3 S cm -1 to 3065 S cm -1 through a treatment with dilute sulfuric acids. PEDOT:PSS films with a sheet resistance of 39 Ω sq -1 and transparency of around 80% at 550 nm are obtained. These PEDOT:PSS films with conductivity and transparency comparable to ITO can replace ITO as the transparent electrode of optoelectronic devices. Copyright © 2012 WILEY-VCH Verlag GmbH & Co.
