title: 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.
