An in-depth description of the chemical structure and the electronic energy state at the ink-jet-printed metal-nanoparticle electrode/organic semiconductor interface is presented. Surface oxygen atoms induce an interface dipole, which leads to an increase in the work function of the printed electrodes, thus facilitating the injection of charge carriers into the organic semiconductor.
