“…Since the prototype of a DSSC was reported in 1991 by O'Regan and Gratzel [2], it has aroused intensive interest and become one of hotspots in solar energy field, because of its ease of fabrication and cost-effectiveness compared with silicon-based photovoltaic devices [3,4]. However, it has been believed that ultraviolet light can degrade the organic dyes in DSSCs in the long term [5].…”

“…[14][15][16] This study transplanted TiO 2 nanotubes thin film onto FTO glass to fabricate front-illuminated DSSC. 17,18 The highly orderly array of TiO 2 nanotubes thin film was easily peeled off from Ti substrate after completion of second anodization processes. This study also compares DSSCs fabricated with similar NH4F concentrations and different reaction times in the anodic oxidation process in terms of their photoelectric conversion efficiency and measures open-circuit voltage decay, electron lifetime, and incident photon-to-electron conversion efficiency (IPCE) of the prepared DSSC.…”

Highly ordered arrays of TiO 2 photoelectrode thin films of dye-sensitized solar cells (DSSCs) were fabricated by anodic oxidation method. This study analyzed the effects of electrolytes under similar NH 4 F concentrations but different reaction times in the anodic oxidation process on the photoelectric conversion efficiency of DSSC, open-circuit voltage decay, electron lifetime, and incident photon-to-electron conversion efficiency (IPCE) of the prepared DSSC. Experimental results show that the TiO 2 nanotube thin film prepared by anodic oxidation with an electrolyte with a NH 4 F concentration at 0.5 wt% and with a reaction time of 5 hr can be fabricated with a length of 17 µm and a photoelectric conversion efficiency of 4.87%, open-circuit voltage of 0.74 V, and short-circuit current density of 13.2 mA/cm 2 . Additionally, the same NH 4 F concentration but with a reaction time of 10 hr achieves a length of 22 µm and a photoelectric conversion efficiency of 6.58%, open-circuit voltage of 0.81 V, and short-circuit current density of 16.1 mA/cm 2 .

“…The decoration of metal oxide nanoneedles with different metal nanoparticles helps increasing and tuning the sensitivity of the resulting nanomaterials towards gases or vapors. Various methods have been used to manufacture pure and metal nanoparticle decorated metal oxide nanoneedles, such as sol-gel [8,9], spray pyrolysis [10], spin-coating [11,12], electrodeposition [13,14], and the aerosol assisted chemical vapor deposition (AACVD) technique [15][16][17][18][19].…”

We report on the aerosol assisted chemical vapor deposition growth of either pure or gold-nanoparticle decorated tungsten oxide nanoneedles, directly integrated onto alumina transducers for achieving resistive gas sensors. The morphology of the different samples grown is studied by scanning electron microscopy and by atomic force microscopy. The performance of these nanomaterials for the detection of methanol, ethanol and acetone vapors at ppm levels is studied. It is found that the detection of these species is possible even in a background of nitrogen where oxygen is present at ppm levels only. The presence of Au nanoparticles on the surface of tungsten oxide nanoneedles significantly increases sensitivity towards the vapors considered. Additionally, Au loading enhances the kinetics of surface reactions and helps decreasing response time. The detection mechanism and the role of Au nanoparticles is discussed in light of the experimental findings.
