The Cover Feature shows that replacement of Zn by Ni in metalloporphyrins used in organic solar cells allows to increase the voltage and to reduce the energy loss. A power conversion efficiency of 10.66% and open‐circuit voltage of 1.06 V are obtained in a device using a Ni‐Por‐based A‐π‐D‐π‐A donor along PC 71 BM as electron acceptor.
