High-efficiency dye-sensitized solar cells based on robust and both-end-open TiO2 nanotube membranes
In the present work, dye-sensitized solar cells (DSSCs) were fabricated by incorporating transparent electrodes of ordered free-standing TiO2 nanotube (TNT) arrays with both ends open transferred onto fluorine-doped tin oxide (FTO) conductive glass. The high-quality TiO2 membranes used here were obtained by a self-detaching technique, with the superiorities of facile but reliable procedures. Af...
متن کاملHigh Efficient Transparent TiO2 Nanotube Dye-Sensitized Solar Cells: Adhesion of TiO2 Nanotube Membrane to FTO by Two Different Methods
In order to fabricate transparent TiO2 nanotube dye-sensitized solar cells, anodically growth nanotube membranes are detached from Ti substrate by a re-anodization method. The membranes are transferred on FTO glass by two different methods. At the first one, 100mM Ti-isopropoxide is used to make TiO2 nanoparticles for adhering TiO2 nanotube membranes to FTO and ...
متن کاملZnO nanotube based dye-sensitized solar cells.
We introduce high surface area ZnO nanotube photoanodes templated by anodic aluminum oxide for use in dye-sensitized solar cells (DSSCs). Atomic layer deposition is utilized to coat pores conformally, providing a direct path for charge collection over tens of micrometers thickness. Compared to similar ZnO-based devices, ZnO nanotube cells show exceptional photovoltage and fill factors, in addit...
متن کاملConical islands of TiO2 nanotube arrays in the photoelectrode of dye-sensitized solar cells
Ti conical island structures were fabricated using photolithography and the reactive ion etching method. The resulting conical island structures were anodized in ethylene glycol solution containing 0.25 wt% NH4F and 2 vol% H2O, and conical islands composed of TiO2 nanotubes were successfully formed on the Ti foils. The conical islands composed of TiO2 nanotubes were employed in photoelectrodes ...
متن کاملAg nanoparticle-deposited TiO2 nanotube arrays for electrodes of Dye-sensitized solar cells
ABSTRACT Dye-sensitized solar cells composed of a photoanode of Ag nanoparticle (NP)-deposited TiO2 nanotube (TNT) arrays were fabricated. The TNT arrays were prepared by anodizing Ti films on fluorine-doped tin oxide (FTO)-coated glass substrates. Efficient charge transportation through the ordered nanostructure of TNT arrays should be carried out compared to conventional particulate TiO2 elec...
