Arrays of GaAs nanowires have been grown by selective-area metal–organic chemical-
vapor deposition (MOCVD) onto photoactive planar Si substrates. This tandem, vertical-wire …

Photoelectrochemical (PEC) water splitting provides an alternative strategy for clean and
renewable hydrogen production; however, the practical application is severely limited by the …

The use of conductive and corrosion-resistant protective layers represents a key strategy for
improving the durability of light absorber materials in photoelectrochemical water splitting …

TiO 2 photoanodes suffer from low catalytic activity and poor stability under acidic media for
water oxidation. Here, we report pH-independent high-efficiency photoelectrochemical …

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 …

Photoelectrochemical (PEC) water splitting into hydrogen and oxygen is a promising
solution for the conversion and storage of solar energy. Because sluggish water oxidation is …

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 …

A low-cost, highly efficient and durable photoelectrochemical (PEC) water-splitting system
can be realized through designing a hierarchical core/shell nanostructured photoanode …

The local pH drop caused by water oxidation inevitably leads to photoanode corrosion and
deactivation. As a well-studied photoanode, the stability of BiVO4 restricts its application …

Light absorbers with moderate band gaps (1–2 eV) are required for high-efficiency solar
fuels devices, but most semiconducting photoanodes undergo photocorrosion or passivation …
