The Back Cover image illustrates oxygen permeation through a metal top electrode in organic photovoltaics. Oxygen molecules can easily penetrate into the metal electrode via nanoscale pinholes formed among metal grains, resulting in oxidation‐induced degradation of devices. This work reports on a simple and effective strategy for reducing the oxygen permeation. Controlling the morphology of metal electrodes enables the electrode by itself to serve as an efficient oxygen barrier. This self‐passivating strategy can greatly improve the environmental stability of devices without complicated additional fabrication steps. More details can be found in the Full Paper by Lee et al. on page 445 in Issue 5, 2016 (DOI: 10.1002/cssc.201501536).
