In situ investigation of dye adsorption on TiO2 films using a quartz crystal microbalance with a dissipation technique

摘要

Dye adsorption plays a crucial role in dye-sensitized solar cells. Herein, we demonstrate an in situ liquid-phase analytical technique to quantify in real time adsorption of dye and coadsorbates on flat and mesoporous TiO2 films. For the first time, a molar ratio of co-adsorbed Y123 and chenodeoxycholic acid has been measured.
