Syntheses of size-varied nanorods TiO2 and blending effects on efficiency for dye-sensitized solar cells

Optimizing the prepared condition of TiO2 1D/3D network structure films to enhance the efficiency of dye-sensitized solar cells

“…[1][2][3][4][5] The conventional photoanodes of DSSCs are made from TiO 2 nanoparticle lms, which suffer from severe photo-generated electron recombination because the interfaces between the nanoparticles can serve as trapping-detrapping sites for electrons. 6,7 In order to overcome this problem, 1D TiO 2 nanorod arrays with a rutile phase are widely utilized as the photoanode, as previous work, [8][9][10][11][12] which can provide a direct electrical pathway and facilitate electron transport. However, a TiO 2 nanorod array photoanode is subject to a vital shortcoming, i.e.…”

Anodic Nanostructures for Solar Cell Applications

“…Apart from the above structures, 1D nanostructures could also serve as light scattering centers, such as nanorods, nanofibers, nanotubes, and their aggregates. For example, the lightto-electricity conversion yield of 6.08% has been achieved by blending of large TiO 2 nanorods (800 nm) and small nanorods (20-40 nm) on the top of small nanorod films, benefit from the low charge transport resistance and high light scattering effect [23]. TiO 2 nanofibers have been readily fabricated by simple electrospinning and applied in DSSCs as photoanode films [24].…”

Photoelectrocatalytic Performances of Nanostructured/Decorated TiO2Electrodes: Effect of Wavelength and Cell Configuration

“…Among the different semiconductors tested to date, TiO 2 is still one of the most attractive photocatalyst because of its appropriate electronic band structure, photostability, chemical inertness, and commercial availability. A huge number of papers appeared in the literature on the synthesis of TiO 2 nano-or microstructures with different morphologies and properties [3][4][5], always addressing the synthesis to obtain a high superficial area: spheres [6], nanorods [7], fibers [8], International Journal of Photoenergy tubes [9][10][11][12][13], sheets [14] have been fabricated. In addition, decorated and hierarchical architectures have been proposed [15][16][17][18][19].…”
