Figure 3From: Effect of compressed TiO2 nanoparticle thin film thickness on the performance of dye-sensitized solar cellsThe UV–vis absorption spectra of compressed TiO 2 NP thin films with various thicknesses. Samples A to F have a photoanode thickness of 12.7, 14.2, 25.0, 26.6, 35.3, and 55.2 μm, respectively, with dye adsorption. Sample D' is the TiO2 NP thin film of 26.6 μm in thickness (the same as sample D) but without dye adsorption.Back to article page
