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.
