A novel transfer‐printing method for high‐performance all‐plastic transparent electrodes is demonstrated. A solution process using H 2 SO 4 not only dramatically enhances the electrical conductivity of poly(3,4‐ethylenedioxythiophene):poly(4‐styrenesulfonate) (PEDOT:PSS) over 4000 S cm −1 but also chemically modifies its adhesion properties, thereby enabling expeditious “pick‐and‐place” transfer onto arbitrary surfaces using elastomeric stamps. Flexible and transparent optoelectronic devices with transferred PEDOT:PSS electrodes show superb performances.
