We report results of density functional theory (DFT) calculations a metal-free dye, 5-(4-sulfophenylazo)salicylic acid disodium salt, known as Mordant Yellow 10 (MY-10), used sensitizer for TiO 2 dye-sensitized solar cells (DSSCs). Given the need to better understand behavior dyes adsorbed on nanoparticle, we studied various single and double deprotonated forms dye bound cluster, taking advantage presence carboxyl, hydroxyl, sulfonic groups possible anchors. discuss binding configurations...
Active semiconductor layers of TiO2 were synthesized via pulsed laser deposition in He, N2, O2, or Ar to manufacture DSSC structures. As-prepared nanostructured coatings grown on FTO photosensitized by the natural absorption N719 (Ruthenium 535-bis TBA) dye fabricate photovoltaic photoanode nanostructures with increased adsorption areas photosensitizer (a combination voluminous media) under different conditions. Systematic SEM, AFM, and XRD investigations carried out study morphological...
Abstract We report results of combined experimental and theoretical studies dye‐sensitized solar cells (DSSCs) using 5‐(4‐sulfophenylazo)salicylic acid disodium salt, known as Mordant Yellow 10 (MY‐10), TiO 2 sensitizer. focus on a single dye but vary the solvent pH solution well photoelectrode preparation conditions to determine for best photovoltaic conversion efficiency. found experimentally that efficiency, measured under standard air mass 1.5 global (AM 1.5G) conditions, was higher in...
The theoretical study of chrysanthemin (cyanidin 3-glucoside) as a pigment for TiO2-based dye-sensitized solar cells (DSSCs) was performed with the GAUSSSIAN 09 simulation. electronic spectra neutral and anionic molecules were calculated by density functional theory B3LYP DGDZVP basis set. A better energy level alignment found partially deprotonated chrysanthemin, excited photoelectron having enough in order to be transferred conduction band TiO2 semiconductor DSSCs. In addition, we used raw...
We report on the fabrication of dye-sensitized solar cells with a TiO2 buffer layer between transparent conductive oxide substrate and mesoporous film, in order to improve photovoltaic conversion efficiency device. The was fabricated by pulsed laser deposition whereas film doctor blade method, using paste obtained sol–gel technique. deposited either oxygen (10 Pa 50 Pa) or argon onto conducting glass kept at room temperature. cross-section scanning electron microscopy image showed...
