Several techniques have been used to prepare titanium dioxide (TiO2) paste from commercially available powders for applications in dye-sensitized solar cells (DSCs). In this study, submicron-sized TiO2 agglomerates with mesopores (2-50 nm) were prepared using a dicarboxylic acid, adipic acid. This type of acid creates new hydroxyl groups that increase the surface area and level of dye adsorption. The adipic acid-added mesoporous TiO2 exhibited light scattering effect at a comparable wavelength with a lower back-scattering efficiency. The effects of the TiO2 paste components, such as the morphology, characteristics and structure, were examined and comparative studies were performed using acetic acid added-TiO2 nanoparticles.
