a  commercial  ti-nanoxide  was  deposited  on  in-doped  sno2 (ito) polymer  substrates by  tape casting  technique with different thicknesses  (7,  14  and  36μm)  to  be  used  as  photoelectrode  in flexible  dye-sensitized  solar  cells  (dsscs).  ruthenium  dye  was adsorbed on each tio2 film for 24 h. the resulting photoelectrodes were used to form flexible dsscs in combination with elec...

In this study, we used the electrochemical anodization to prepare TiO2 nanotube arrays and applied them on the photoelectrode of dye-sensitized solar cells. In the field emission scanning electron microscopy analysis, the lengths of TiO2 nanotube arrays prepared by electrochemical anodization can be obtained with approximately 10 to 30 μm. After titanium tetrachloride (TiCl4) treatment, the wal...

Nanostructured metal oxide semiconductors have shown outstanding performances in photoelectrochemical (PEC) water splitting, but limitations in light harvesting and charge collection have necessitated further advances in photoelectrode design. Herein, we propose anodized Fe foams (AFFs) with multidimensional nano/micro-architectures as a highly efficient photoelectrode for PEC water splitting. ...

Hierarchical macroporous Zn(2)SnO(4) consisting of nanoparticles has been synthesized for the first time through an in situ hydrothermal and a following annealing process in the presence of a polystyrene (PS) template. Zn(2)SnO(4) macropore sizes are tuned in the range of 180-650 nm by selecting the appropriate size of PS spheres, and the building unit size of the Zn(2)SnO(4)macropore is 4.2 nm...

Stainless steel based dye solar cells have been upscaled from small, laboratory size test cells of 0.32 cm2 active area to 6 cm x 6 cm "mini-modules" with active areas ca. 15 cm2. Stainless steel works as the photoelectrode substrate whilst the counter electrode is prepared on indium-doped tin oxide coated polyethyleneterephtalate or polyethylenenaphtalate plastic foil (fluorine-doped tin oxide...

Oxide nanowire arrays were studied for their applications to solar cells. It was demonstrated that the nanowires could provide direct pathways for electron transport in dye-sensitized solar cells and therefore, while forming photoelectrode films, they offered better suppression of charge recombination than nanoparticles. However, the photoelectron films consisting of nanowires suffered a disadv...

This study highlights the utilization of Cr2S3-Cr2O3/P2ABT nanocomposite photoelectrode for efficient and highly sensitive photon absorption, enabling generation green hydrogen through production hot electrons upon illumination. The is synthesized via a one-pot reaction using K2Cr2O7 2-aminobenzene-1-thiol monomer, presence Cr2S3-Cr2O3 confirmed by XRD XPS analysis within composite. optical pro...
