Vertically aligned, free standing p‐Si nanowire arrays of varying lengths are grown on p‐Si wafers and coupled with Sn nanoparticles. As reported by Sang Min Ji, Hyunwoong Park, and co‐workers in article number 1301614, these heterojunction wire/Sn arrays increase the production of formate by more than 10 and 5 times compared to planar p‐Si and wire arrays, respectively, with Faradaic efficiencies of ≈40% in a single cell.
