碩士 === 國立中山大學 === 化學系研究所 === 97 === In my research, I use sucrose to modify TiO2 nanoparticles to study the influence of sucrose modification in the performance of dye-sensitized solar cell. Two types of TiO2 are used in the experiments, one is P-25 (80% anatase, Degussa, Germany) and the other is ST-21 (100% anatase, Ishihara Sangyo, Japan). The results shows that the solar cells with TiO2 photoanode sintered in N2 has better conversion efficiency than that sintered in air. On the other hand, the TiO2 with 0.08 g/mL sucrose modification and sintered in N2 has the best conversion efficiency than the others with different sucrose concentration modifications and the highest conversion efficiency reaches 5.55 %. The performance of P-25 with 0.08 g/mL sucrose made solar cell is 10.9% higher than that without sucrose modification TiO2 photoanode made solar cell and the performance of ST-21 with 0.08 g/mL sucrose made solar cell is 5.4% higher than that without sucrose modification.
