The dye-sensitized solar cell (DSSC) is a device for the conversion of visible light into electricity which uses the photoelectrochemical system that is made up of a semiconductor that is formed between a photosensitized anode and an electrolyte. It is based on the sensitization of wide bandgap semiconductors. The DSSCs are categorized as the solar cells of the next generation for their low manufacturing costs compared with the silicon type of solar cells. In DSSC, titanium dioxide (TiO2) is one of the suitable material used for nano-porous thin film since it has appropriate energy levels, high dye adsorption ability, and low cost, and it is easy to prepare. Extensive research on the photochemistry and photophysics of TiO2-based DSSCs has shown that the light-harvesting efficiency of TiO2 is influenced by its crystalline phase, particle size, as well as its surface area, dye affinity, and film porosity. In this research, we have focused on the dye and its effect on the light scattering of TiO2 particles and the best condition of TiO2 particles in order to improve solar energy conversion efficiency. The best condition for TiO2 particles, which were sintered at 450 °C for 60 min, resulted from the use of the spin-coating method. On the other hand, the best dye is anthocyanin (blueberry), and the best condition was to keep it for 6 h, at 21 °C, in a dark environment.
