Cooperation of multifunction composite structures and fluorescein for photovoltaic performance-enhanced ZnO-based dye-sensitized solar cells

A composite catalyst of reduced black TiO2−x/CNT: a highly efficient counter electrode for ZnO-based dye-sensitized solar cells

“…The doctor blade technique was used to fabricate ZnO photoanode films. 4,5,28 The photoanode films were heated at 250 °C for 120 min. and then sensitized with 0.5 mM N719 in absolute ethanol solution at 45 °C for 120 min.…”

NbCl5‐Promoted Synthesis of Fluorescein Dye Derivatives: Spectroscopic and Spectrometric Characterization and Their Application in Dye‐Sensitized Solar Cells

“…Furthermore, Zhang et al. obtained the best performances ( η =6.54 %) by using ZnO nanoparticles with different morphologies sensitized with xanthene dyes plus ascorbic acid …”

“…Metal‐free dyes have emerged as an alternative to metallic complexes dyes, achieving, in some devices, efficiencies up to 13 % . Fluorescein derivatives have already been used as sensitizers, exhibiting good power conversion efficiency and promising applications as sensitizers in DSSCs owing to excellent performance in terms of fluorescence excitation . Also, Kanmani et al.…”

Investigation of Vegetable Tannins and Their Iron Complex Dyes for Dye Sensitized Solar Cell Applications

“…Furthermore, the absorption spectra of tannins and their complexes and diffused reflectance spectra (DRS) of ZnO nanoplates were recorded in Shimadzu UV-2600 PC spectrophotometer. To determine the dye amount, the adsorbed dye was desorbed with 1M NaOH solution and then measured spectrophotometrically [29]. The characteristic peaks of tannin and Fe-tannin complex dyes were revealed by using a Perkin-Elmer Spectrum Two FTIR spectrometer equipped with a diamond crystal ATR accessory in the range of 500-4000 cm -1 .Cyclic voltammetry measurements were carried out in acetonitrile solution of 0.1 M LiClO 4 by employing a computer-controlled CHI 660C electrochemical workstation with a traditional three electrode system.…”

“…Additionally, lattice strain dependent on external compressive stress of (101), (002), (100) peaks are calculated 0.13, 0.05, 0.11%for ZnO nanoplate and 0.19, 0.11, 0.14% for FTO-ZnO, respectively with the average lattice strain of 0.07% for ZnO nanoplates and of 0.13% for FTO-ZnO. The Debye-Scherer method is commonly used to determine the crystalline size, but this method does not include the peak broadening [29,30]. In this regard, crystalline size and strain calculation of ZnO nanoplate and FTO-ZnO photoanode can be carried out by using Williamson Hall Plot.…”
