Controlled Assembly of Nanorod TiO2 Crystals via a Sintering Process: Photoanode Properties in Dye-Sensitized Solar Cells

Figure 4

SEM images of the TiO2 film after sintering. The TiO2 nanofluid was spread on substrate, using spin coating method. The concentrations of SA-TiO2 and BR-TiO2 were, respectively, 20 wt% and 20 wt%.
