Facile Preparation of TiO2 Nanobranch/Nanoparticle Hybrid Architecture with Enhanced Light Harvesting Properties for Dye-Sensitized Solar Cells

The UV-Vis absorption spectra of the dye (N719) detached from the TiO2 films prepared under a varied number of TiCl3 treatments. To measure the UV-Vis absorption spectra of the dye (N719), it was first desorbed by an ammonium (NH4OH) solution in water and ethanol (50 : 50, v/v).
