High‐performance dye‐sensitized solar cells with nitrogen‐doped graphene foams as the counter electrode are used for the efficient conversion of solar light into electricity. In their Communication on page 12124 ff., J. Qu, L. Dai, et al. show the application of the foam as a metal‐free electrocatalyst for the reduction of triiodide, leading to a power conversion efficiency up to 7.07 %.
