On-Fabrication Solid-State N-Doping of Graphene by an Electron-Transporting Metal Oxide Layer for Efficient Inverted Organic Solar Cells

On‐fabrication solid‐state N‐doping of graphene is developed using a Zonyl‐added ZnO layer on a graphene surface. Inverted organic solar cells based on the graphene cathode and the ZnO layer exhibit a power conversion efficiency of 7.5%—a high‐record power conversion efficiency of single‐junction or...

Zusammenfassung:On‐fabrication solid‐state N‐doping of graphene is developed using a Zonyl‐added ZnO layer on a graphene surface. Inverted organic solar cells based on the graphene cathode and the ZnO layer exhibit a power conversion efficiency of 7.5%—a high‐record power conversion efficiency of single‐junction organic solar cells with graphene electrodes. For the first time 100% power conversion efficiency with respect to the ITO cathode is achieved.
