Down to the wires: A highly efficient artificial photosynthetic system employing hydrogen‐terminated silicon nanowires is reported. The nanowires enable a cascading electron transfer from electron donor to NAD + via a rhodium‐based electron mediator. Approximately 80 % of NADH is photoregenerated from NAD + by the nanowires during 2 h of light irradiation, and successfully coupled with the photoenzymatic synthesis of L ‐glutamate.
