Der Einbau einzelner aktiver Cobaltzentren in eine Graphenmatrix ergibt eine aktive und stabile Gegenelektrode für die Redoxreaktion I−/I3−. In der Zuschrift auf S. 6820 ff. zeigen D. Deng, W.‐H. Zhang et al. zudem, dass die Verwendung dieser Gegenelektrode anstelle einer Platingegenelektrode in Farbstoffsolarzellen (DSSCs) eine effizientere Stromumwandlung zur Folge hat.
The design of catalysts that are both highly active and stable is always challenging. Herein, we report that the incorporation of single metal active sites attached to the nitrogen atoms in the basal plane of graphene leads to composite materials with superior activity and stability when used as counter electrodes in dye‐sensitized solar cells (DSSCs). A series of composite materials based on different...
