摘　　要：以商业TiO2纳米粉(P25)为原料,将其充分研磨得到胶体,用刮涂和热处理的方法在氟掺杂氧化锡导电玻璃基底上制备TiO2纳米多孔薄膜阳极,并组装成染料敏化太阳能电池(DSSC)。对TiO2膜进行X射线衍射、扫描电镜表征分析,并对所制备的DSSC进行光电性能测试。采用正交实验设计优化制备TiO2胶体时乙酰丙酮、OP乳化剂、蒸馏水的量和研磨时间,并讨论其对DSSC性能的影响。用在最优参数下所得胶体制备的DSSC的光电转换效率最高,约为4.51%。The porous, nano-crystalline TiO2 coatings, used as anode materials of the dye-sensitive solar cells （DSSC）, were deposited by sol-gel technique on substrate of fluorine-doped tin oxide （FID） conductive glass. The syn- thesis conditions of TiO2 gel, including the concentrations of acetylancetone, emulsifying agent OP, and aqua destiflata, as well as the grinding time of the commercial TiO2 powder （P25）, were optimized by orthogonal experimental design. The microstructures and photoelectric properties of the TiO2 coatings were characterized with X-my diffraction, and scanning electron microscopy. The best photoelectric conversion efilciency of the prototyped DSSC, fabricated with the pomns TiO2 coatings deposited under the optimized conditions, was found to be up to 4.51%.
