Abstract Photoelectrochemical properties have been investigated for flexible photoelectrodes containing 310 nm thick ZnO film on spin-coated ITO/PET. The high crystalline structure of was studied using x-ray diffraction pattern. A value 3.4 eV has estimated optical band gap from its absorption spectra. photoelectrode demonstrated to generate photoelectrochemical current. photocurrents are enhan...

J Abstract We report here a successful fabrication of a 3-D photoelectrode configuration having hydrothermally formed TiO2 nanotubes on parallel Ti fins. The Ti fin arrays were assembled by simple and facile spot welding of alternately tall and short Ti foil assembly, which provides signific...
A high-throughput method has been developed using a commercial piezoelectric inkjet printer for synthesis and characterization of mixed-metal oxide photoelectrode materials for water splitting. The printer was used to deposit metal nitrate solutions onto a conductive glass substrate. The deposited metal nitrate solutions were then pyrolyzed to yield mixed-metal oxides that contained up to eight...
A prototype photoelectrode has been fabricated using a GaN nano-pyramid array structure grown on a cost-effective Si (111) substrate, demonstrating a significant improvement in performance of solar-powered water splitting compared with any planar GaN photoelectrode. Such a nano-pyramid structure leads to enhanced optical absorption as a result of a multi-scattering process which can effectively...
