Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A photoelectrode comprising an electrode at least partially formed of an oxide comprising a cubic rocksalt crystal structure of FeO combined with at least one of lithium, hydrogen, sodium, magnesium, manganese, zinc, or nickel, wherein the band gap of the oxide is between and including 1.3 eV and 2.5 eV. 2. The photoelectrode of claim 1 , wherein the electrode is combined with at least one of hydrogen, lithium, or sodium. 3. The photoelectrode of claim 1 , wherein the electrode is alloyed with at least one of magnesium, and manganese, zinc, or nickel. 4. The photoelectrode of claim 2 , wherein the electrode is combined with hydrogen, lithium, and sodium. 5. The photoelectrode of claim 3 , wherein the electrode is alloyed with magnesium (II) oxide, manganese (II) oxide, zinc (II) oxide, or nickel (II) oxide. 6. The photoelectrode of claim 2 , wherein lithium is configured such that the lithium will not trap holes. 7. The photoelectrode of claim 2 , wherein the hydrogen is configured such that the hydrogen will not trap holes. 8. The photoelectrode of claim 2 , wherein the sodium is configured such that the sodium will not trap holes.
