title: Transfer-Printed PEDOT:PSS Electrodes Using Mild Acids for High Conductivity and Improved Stability with Application to Flexible Organic Solar Cells.
abstract: Highly conductive, flexible, and transparent electrodes (FTEs) of
  PSS films on plastic substrates have been achieved using strong acid treatments. However, it is rare to realize a performance attenuation of
  PSS FTEs on plastic substrates and flexible optoelectronic devices because of strong acid residues in the
  PSS matrix. Herein, we develop a feasible transfer-printing technique using mild acids. Because of a mild and weak property of these acids and less acid residues in
  PSS matrix, the transferred
  PSS FTEs exhibited a significant enhancement in stability, conductivity (3500 S cm(-1)), transparency, and mechanical flexibility on plastic substrates. Flexible organic solar cells with the FTEs also showed a remarkable enhancement in power conversion efficiency and stability in the ambient atmosphere. It is expected that the novel transfer-printing technique for making
  PSS FTEs is also useful in many other types of flexible optoelectronic devices.
