Abstract

Abstract : The incorporation of single cobalt active sites within a graphene matrix leads to a composite material with superior activity and stability when used as a counter electrode for the interconversion of the redox couple I − /I3 − . In their Communication onpage 6708 ff., D. Deng, W.‐H. Zhang, and co‐workers further show that the use of this material as a counter electrode in a dye‐sensitized solar cell (DSSC) leads to a better power conversion efficiency than the use of a platinum counter electrode.
