Here, we present flexible, transparent, and highly conductive ultra-thin silver films to be applied as a bottom electrode for flexible organic electronics. We show that ultra-thin nuclei inducers such as an amine-containing nonconjugated polyelectrolytes improve the morphology of the thermally evaporated silver films on the dielectric substrates. By capping a conductive polymer layer as a facile antireflection layer, we obtain high quality flexible and transparent electrodes with thicknesses of ~ 9 nm, which exhibit transmittance of 92% at 550 nm and a superior sheet resistance of 9 Ω/□. In application, we apply these flexible and transparent conducting films in polymer light-emitting diodes. The maximum current efficiency and power efficiency of these flexible devices are comparable to efficiencies of ITO-bottom electrode devices. |
