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.
