将涂有TiO2纳米晶膜的导电玻璃浸渍于氟钛酸铵、硼酸和水的液相沉积(Liquid Phase Deposition,简称LPD)反应溶液中,利用反应液中氟的金属配位离子和金属氟化物之间的化学平衡反应,在TiO2纳米晶多孔膜(简称ncTiO2膜)上沉积一层TiO2纳米粒子,从而实现对TiO2纳米晶膜进行化学处理.以经过LPD处理的TiO2纳米晶膜作为光阳极组装染料敏化太阳能电池(DSSC)并测试其伏安特性曲线,研究了不同反应时间条件下LPD处理ncTiO2膜对DSSC光电性能的影响.结果表明:在一定条件下用LPD处理TiO2纳米晶膜可显著提高其DSSC光电性能,短路电流密度最高提高13.13％,能量转化效率最高提高13.95％.论文对LPD处理TiO2纳米晶膜提高DSSC光电转化性能的原因进行了分析.
