Possessing the advantages of transparency, con-ductivity, and flexibility, graphene is a serious alter-native to indium tin oxide (ITO) electrodes in solar cells and may serve as a sustainable electrode. By performing interface engineering of layer-by-layer stacked graphene on glass, Kian Ping Loh and co-workers demonstrate on p. 1514 that organic solar cells with a power conversion efficiency approaching that of ITO can be attained.
