Soluble Self‐Doped Conducting Polymer Compositions with Tunable Work Function as Hole Injection/Extraction Layers in Organic Optoelectronics

Abstract

Making light work: Polymer-based compositions with a perfluorinated ionomer (PFI) as hole injection/extraction layers are introduced for organic LEDs and organic photovoltaic cells. The work functions of the layers formed by single spin-coating could be tuned to improve device efficiency and device lifetime. The effects of the PFI surface layers on charge injection/extraction and device lifetime were investigated.
