Abstract

In the present work, electrochemical anodization has been used to prepare uniform TiO{sub 2} nanotube array photoelectrode. The average internal diameter, tube length and wall thickness of the optimized morphology is {approx}180 nm, 14 {mu}m and 10 nm, respectively. It was found that the tube diameter increases with the anodization voltage. Diffraction data reveals that the nanotubes consist solely of anatase phase. Back illuminated geometry of dye-sensitized solar cell (DSSC), with nanotubes grown at 60 V for 2 h, gave a cell performance of 4.5%. TiO{sub 2} nanotubes are loaded with silver (Ag) nanoparticles synthesized by a hydrothermal route. The Ag particle size is controlled resulting in solar conversion efficiency to increase by 22%. The DSSC based on TiO{sub 2} nanotube with Ag nanoparticles shows power conversion efficiency of 5.5%. Detailed characterization are performed, presented and discussed. - Graphical abstract: Enhanced solar conversion efficiency of dye-sensitized solar cells by decorating TiO{sub 2} nanotube array with Ag nanoparticles. Highlights: Black-Right-Pointing-Pointer Uniform array of TiO{sub 2} nanotubes synthesized via electrochemical anodization.

Synthesis of ZnO-TiO{sub 2} core-shell long nanowire arrays and their application on dye-sensitized solar cells

Journal Article Yamin, Feng; Xiaoxu, Ji; Jinxia, Duan; ... - Journal of Solid State Chemistry

Long ZnO nanowire arrays (NAs) grown on fluorine-doped tin oxide (FTO) glasses have been synthesized via a facile hydrothermal method without refreshing the reaction solution and applied as the precursor. By adjusting growth conditions, ZnO NAs with tunable lengths can be achieved. A nanocomposite made of ZnO nanowire core and TiO{sub 2} shell was further realized by a novel 'fast-dip-coating' method conducted in a Ti(OC{sub 4}H{sub 9}){sub 4}-dissolved ethanol solution. The formed ZnO-TiO{sub 2} core-shell NAs on FTO substrates were applied as electrodes for dye sensitized solar cells (DSSCs). It is found that both the TiO{sub 2} coating and NAsmore »« less

P25 niblet-like coated on large void space TiO{sub 2} nanotubes arrays for high-rate charge-collection and improved photoconversion efficiency

Journal Article Lixia, Xiao; Gaopeng, Dai; Zhengcai, Xia - Journal of Solid State Chemistry

A niblet-like P25-coated large void space TiO{sub 2} nanotubes arrays (PCTs) has been synthesized by decorating P25 nanoparticles on a rapidly-synthesized large void space TiO{sub 2} nanotube arrays (LTAs) with an appropriate hydrothermal treatment approach in a Teflon-lined stainless steel autoclave. Some key factors and probable synthetic mechanisms have been investigated to obtain an optimal route. Exhilaratingly, the as-synthesized PCTs and LTAs show impressive morphologies, structures and very large void space. And the most important is that, compared with LTAs, the decorated PCTs demonstrates significantly improved dye loading and high-rate charge-collection capability and thus leads to a more than doublemore »« less

Performance improvement of P3HT/TiO{sub 2} coaxial heterojunction polymer solar cells by introducing a CdS interface modifier

Journal Article Li, Yan; Wang, Cheng-Wei; Zhao, Yun; ... - Journal of Solid State Chemistry

Coaxial heterojunction polymer solar cells consisting of vertical aligned crystalline TiO{sub 2} nanotube arrays transferred onto FTO-coated glass and ordered interpenetrating poly(3-hexylthiophene-2,5-diyl) (P3HT) have been fabricated through interface sensitization of CdS quantum dots on TiO{sub 2} nanotube walls. The performances of structurally identical polymer solar cells with and without CdS quantum dots sensitization were investigated and compared. The sensitized P3HT/CdS-TiO{sub 2} cell demonstrated an open-circuit photovoltage of 0.72 V and a short-circuit current of 8.29 mA/cm{sup 2} while the P3HT/TiO{sub 2} cell was 0.41 V and 5.64 mA/cm{sup 2}. The efficiency of this sensitized cell represents a more than four-foldmore »« less

Photoelectrochemical water splitting and simultaneous photoelectrocatalytic degradation of organic pollutant on highly smooth and ordered TiO{sub 2} nanotube arrays

Journal Article Hongjun, Wu - Journal of Solid State Chemistry

The photoelectrochemical water splitting and simultaneous photoelectrocatalytic degradation of organic pollutant were achieved on TiO{sub 2} nanotube electrodes with double purposes of environmental protection and renewable energy production under illumination of simulated solar light. The TiO{sub 2} nanotube arrays (TiO{sub 2} NTs) were fabricated by a two-step anodization method. The TiO{sub 2} NTs prepared in two-step anodization process (2-step TiO{sub 2} NTs) showed much better surface smoothness and tube orderliness than TiO{sub 2} NTs prepared in one-step anodization process (1-step TiO{sub 2} NTs). In the photoelectrochemical water splitting and simultaneous photoelectrocatalytic decomposition process, the 2-step TiO{sub 2} NTs electrode showedmore »« less
Enhanced performance of dye-sensitized solar cells based on TiO{sub 2} with NIR-absorption and visible upconversion luminescence

Journal Article Liang, Li; Yulin, Yang; Mi, Zhou; ... - Journal of Solid State Chemistry

TiO{sub 2} with NIR-absorption and visible upconversion luminescence (UC-TiO{sub 2}) is prepared by a sol-gel method and calcined at 700 Degree-Sign C for 6 h. The material broadens the response region of dye sensitized solar cells (DSSCs) from an ultraviolet-visible region to the whole region of the solar spectrum. It shifts NIR sunlight to visible light which matches the strong absorbing region of the dye (N719). DSSCs based on UC-TiO{sub 2} achieved higher conversion efficiency than that on raw TiO{sub 2}. UC-TiO{sub 2} was mixed with commercial raw TiO{sub 2} as additive, and the short-circuit current density, open-circuit voltage andmore »« less
