“…Due to the existence of stainless meshes and the difference of spacing sizes of them, the loading amount of sprayed precursor droplets onto the substrate was varied for each sample. Thus, for comparison, we adjusted the deposition time (15,35,30, and 25 min for the bare FTO, 60M-FTO, 40M-FTO, and 24M-FTO) to collect FTO samples with similar sheet resistance (~8 Ω/□).…”

“…Moreover, the TCO can be used for photocatalysis application due to its advantageous electronic properties and conductivity [10][11][12][13]. For example, Khalaf et al demonstrated the photocatalytic behavior of Co-doped TiO2, and Jiamprasertboon et al reported the optimized photocatalytic properties of Cl-doped ZnO films with enhanced electrical and optical properties [14,15]. At this point, enhancing the electrical conductivity and transmittance of the TCO is suggested as one of the most effective strategies for improving the electro-chromic and photocatalytic performances.…”

In this study, the surface morphology of net-patterned fluorine-doped tin oxide (FTO) films was optimized with mesh sizes (60 mesh, 40 mesh, and 24 mesh) using the one-pot horizontal ultrasonic spray pyrolysis deposition (HUSPD) process. The 40M-FTO sample exhibited optimized electrical and optical properties due to the improved crystallinity and net-patterned surface morphology of FTO. The electrochromic (EC) electrodes fabricated with 40M-FTO showed superior EC performance, including transmittance modulation (ΔT, 58.7%), switching speeds (4.1 s for coloration and 5.9 s for bleaching), and coloration efficiency (CE, 52.4 cm2/C). These optimum values were attributed to the combined effect of the enhanced electrical properties from the improved crystallinity of the SnO2 and the high transmittance with a large surface area stemming from the optimization of the net-patterned FTO surface morphology. Moreover, the improved reaction sites with large surface area and enhanced electrical conductivity can facilitate the photocatalytic reaction. Accordingly, we suggest our novel strategy for use in creating promising transparent conducting electrodes that can be fabricated with net-patterned FTO to realize enhanced electrochromic and photocatalytic interface reactions.
