Transparent ALD-grown Ta2O5 protective layer for highly stable ZnO photoelectrode in solar water splitting.
نویسندگان
چکیده
This communication describes a highly stable ZnO/Ta2O5 photoanode with Ta2O5 deposited by atomic layer deposition. The ultrathin Ta2O5 protective layer prevents corrosion of ZnO and reduces surface carrier recombination, leading to a nearly two-fold increase of photo-conversion efficiency. The transparency of Ta2O5 to sunlight is identified as the main reason for the excellent stability of the photoelectrode for 5 hours.

Discovery of Overcoating Metal Oxides on Photoelectrode for Water Splitting by Automated Screening.
We applied an automated semiconductor synthesis and screen system to discover overcoating film materials and optimize coating conditions on the BiVO4/WO3 composite photoelectrode to enhance stability and photocurrent. Thirteen metallic elements for overcoating oxides were examined with various coating amounts. The stability of the BiVO4/WO3 photoelectrode in a highly concentrated carbonate elec...
متن کاملTantalum nitride films integrated with transparent conductive oxide substrates via atomic layer deposition for photoelectrochemical water splitting.
Tantalum nitride, Ta3N5, is one of the most promising materials for solar energy driven water oxidation. One significant challenge of this material is the high temperature and long duration of ammonolysis previously required to synthesize it, which has so far prevented the use of transparent conductive oxide (TCO) substrates to be used which would allow sub-bandgap light to be transmitted to a ...

Atomic layer deposition (ALD) is a technique that uses a cyclical exposure and purging of chemical precursors to create thin films. ALD offers a high degree of control over the thickness and composition of the films. The technique is generally used for binary compounds such as oxide and nitrides. ZnO is grown by ALD as a transparent conductive oxide for photovoltaic and optoelectronic applicati...
متن کاملThe influence of structure and processing on the behavior of TiO2 protective layers for stabilization of n-Si/TiO2/Ni photoanodes for water oxidation.
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 in aqueous solution. Amorphous TiO2 deposited by atomic-layer deposition (ALD) onto various n-type semiconductors (Si, GaAs, GaP, and CdTe) and coated with thin films or islands of Ni produces efficient, stable photoanod...

Nanostructured metal oxides are one of key factors in determining the PCE of DSCs, becau...
