Abstract
UNLABELLED: Highly conductive, flexible, and transparent electrodes (FTEs) of
PEDOT: PSS films on plastic substrates have been achieved using strong acid treatments. However, it is rare to realize a performance attenuation of
PEDOT: PSS FTEs on plastic substrates and flexible optoelectronic devices because of strong acid residues in the
PEDOT: 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
PEDOT: PSS matrix, the transferred
PEDOT: 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
PEDOT: PSS FTEs is also useful in many other types of flexible optoelectronic devices.
