A Si Photocathode Protected and Activated with a Ti and Ni Composite Film for Solar Hydrogen Production

An efficient, stable and scalable hybrid photoelectrode for visible‐light‐driven H2 generation in an aqueous pH 9.2 electrolyte solution is reported. The photocathode consists of a p‐type Si substrate layered with a Ti and Ni‐containing composite film, which acts as both a protection and electrocata...
