We fabricated dye-sensitized solar cells including fluorinated gel electrolyte and studied about the relationship between the performance of the solar cells and the aggregation state of TiO₂ nano-particles on electrodes. As for the performance of the cell, the I-V characteristics were measured under irradiation. The combination of TiO₂ nanoparticles with different size plays an important role in bringing unevenness to realize a large surface area, which is critical for the high performance of the cells.
