In Situ Growth of a ZnO Nanowire Network within a TiO₂ Nanoparticle Film for Enhanced Dye‐Sensitized Solar Cell Performance

Abstract

ZnO nanowire networks featuring excellent charge transport and light scattering properties are grown in situ within TiO(2) films. The resultant TiO(2) /ZnO composites, used as photoanodes, remarkably enhance the overall conversion efficiency of dye-sensitized solar cells (DSSCs) by 26.9%, compared to that of benchmark TiO(2) films.

Ambient Aqueous Growth of Cu2Te Nanostructures with Excellent Electrocatalytic Activity toward Sulfide Redox Shuttles

“…The Cu 2 Te counter electrodes (CEs) were fabricated by depositing various pastes on fluorine‐doped tin oxide (FTO) substrates using the doctor blade technique 41, 52. Then, the newly formed films were annealed at 350 °C for 30 min in Argon atmosphere.…”

Dye-sensitized photoelectrochemical cell on plasmonic Ag/AgCl @ chiral TiO 2 nanofibers for treatment of urban wastewater effluents, with simultaneous production of hydrogen and electricity

“…The fast photodegradation of the TOC 17 including EE2 should be attributed to the combined effect of (i) the strong 18 photocatalytic activity of irradiated Ag/AgCl @ chiral TiO 2 nanofibers and of (ii) the pairs in the Ag nanoparticles due to surface plasmon resonance (SPR) [26]. In this helical structure, probably yielding superoxide radicals and finally HO· radicals from 7 the reductive pathway, as reported with other dyes [28]. However, this effect seems Fig S5).…”

“…Finally, the photoanode was gradually heated at 80 °C for 15 min and then at 500 °C for 30 min. The thickness of the film (11 μm) was increased by repeating this doctor-blade technique [28]. Table S1 (SI).…”

“…The current-voltage (J-V) characteristics of the 12 cells were measured as described elsewhere [28]. The amount of hydrogen, the concentrations of EE2, TOC, TN and were measured as shown in our previous studies [4,14,29].…”

Controllable synthesis of concave cubic gold core–shell nanoparticles for plasmon-enhanced photon harvesting

“…The working electrode films were fabricated by the doctor-blading method using P25 pastes and P25 pastes incorporating Au@TiO 2 NPs as described in our previous work. 27 The working electrodes were then put into a muffle furnace and gradually heated at 325 °C for 5 min, at 375 °C for 5 min, at 450 °C for 15 min, and at 500 °C for 15 min. The resultant working electrodes prepared from P25 paste and P25 incorporating core-shell NPs (CA@T-1, CA@T-2, CA@T-3, CA@T-4, and SA@T) were denoted as P25, C1, C2, C3, C4, and S, respectively.…”
