Abstract:
Herein, hydrogenated amorphous Si (a‐Si:H) covered with a thin layer of CoO x is applied as photoanode for PEC water splitting. The thin layer of CoO x effectively protects a‐Si:H from the corrosive electrolyte and quantitative oxidation of water to oxygen was observed. A high applied bias photon‐to‐current efficiency of 2.34 % was achieved using an intrinsic absorber and an additional p‐type layer. This work shows that a‐Si:H with a sandwich‐like structure, in which each layer has its own functionality, can be applied as an efficient and stable photoanode for PEC water oxidation.
