Crystalline poly(3,4‐ethylenedioxythiophene) poly(styrenesulfonate) (PEDOT:PSS) nanofibrils with an electrical conductivity of 4380 S cm ‐1 are formed via a solution process using H 2 SO 4 . The concentrated H 2 SO 4 treatment induces a significant structural rearrangement of the PEDOT:PSS via a charge‐separated transition mechanism, resulting in highly ordered and densely packed PEDOT:PSS nanofibrils. The PEDOT:PSS electrode shows a sheet resistance of 46 Ω sq ‐1 with 90% optical transmittance.
