The present invention provides a photo-electrochemical (PEC) cell electrode having a surface portion and a bulk portion composed of the same material, wherein at least one of the bulk portion and the surface portion of the electrode is doped with at least one dopant, and wherein said doping is non-uniform along an axis perpendicular to the surface portion. The non-uniform doping can include different concentrations and/or types of the dopants in the bulk portion and in the surface portion of the electrode. There is further provided a PEC cell comprising said electrode and an electrolyte, wherein the surface portion of the electrode faces the electrolyte.

Non-uniform doping of photoelectrochemical cell electrodes

A photoelectrode, photovoltaic device and photoelectrochemical cell and methods of making are disclosed. The photoelectrode includes an electrode at least partially formed of FeO combined with at least one of lithium, hydrogen, sodium, magnesium, manganese, zinc, and nickel. The electrode may be doped with at least one of lithium, hydrogen, and sodium. The electrode may be alloyed with at least one of magnesium, manganese, zinc, and nickel.
