A high conductivity and cost effective polyaniline (PANI) based film was prepared for a flexible electrode. A self assembly structure is selected according to the various analyses such as self-assembled degree, crystallinity, and the blending properties with PANI. The additive, named self-assembly supramolecules (SAS), was successfully blended with PANI chains. PANI film blended with the optimum SAS (PANI:CSA/SAS18) exhibited high conductivity of 843 S/cm. The flexible organic solar cells (OSCs) device adapted to our electrode shows a high power conversion efficiency of 1.73%. In addition, the efficiency of our OSCs device remains more than 90% after 500 hours. It means that our device had long environmental stability under numerous device operating cycles. The PANI based electrode has the potential for consideration as a novel polymer electrode in a flexible display.
