Toward Simultaneous Achievement of Outstanding Durability and Photoelectrochemical Reaction in Cu2O Photocathodes via Electrochemically Designed Resistive Switching

Photoelectrochemical (PEC) cells using Cu2O, semiconductor photoabsorbers passivated by protection layers, show a trade‐off between high photocurrent and stability because of the thickness of the energy band transport along the conduction band. Based on nanofilaments with non‐volatile metal‐like cur...
