Reactively sputtered nickel oxide (NiOx) films provide transparent, antireflective, electrically
conductive, chemically stable coatings that also are highly active electrocatalysts for the …

Small-band-gap (E g< 2 eV) semiconductors must be stabilized for use in integrated devices
that convert solar energy into the bonding energy of a reduced fuel, specifically H 2 (g) or a …

Semiconductors with small band gaps (< 2 eV) must be stabilized against corrosion or
passivation in aqueous electrolytes before such materials can be used as photoelectrodes …

Achieving stable operation of photoanodes used as components of solar water splitting
devices is critical to realizing the promise of this renewable energy technology. It is shown …

A reactively sputtered NiOx film has been used here to stabilize a buried-junction p+ n-InP
photoanode from anodic dissolution/corrosion for> 48 h of continuous light-driven evolution …

Conductive, amorphous TiO2 coatings deposited by atomic-layer deposition, in combination
with a sputter deposited NiCrOx oxygen-evolution catalyst, have been used to protect Si …

Photoelectrodes without ap–n junction are often limited in efficiency by charge
recombination at semiconductor surfaces and slow charge transfer to electrocatalysts. This …

Although II–VI semiconductors such as CdS, CdTe, CdSe, ZnTe, and alloys thereof can have
nearly ideal band gaps and band-edge positions for the production of solar fuels, II–VI …

We report a nickel oxide (NiOx) thin film, from a cost-effective sol–gel process, coated n-type
silicon (n-Si) as a photoanode for efficient photo-oxidation of water under neutral pH …

Silicon's sensitivity to corrosion has hindered its use in photoanode applications. We found
that deposition of a~ 2-nanometer nickel film on n-type silicon (n-Si) with its native oxide …
