| 摘 要： | 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nc-TiO2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nc-TiO2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。

| Abstract: | A conductive glass coated with porous nano-crystalline-TiO2 films was immersed in a LPD solution containing titanium ammonium fluoride,boric acid and water,and a layer of TiO2 was deposited on the surface of the porous TiO2 films through the hydrolysis of titanium ammonium fluoride,the F-of which react with boric acid forming BF4,shifting the hydrolysis equilibrium to form TiO2.The TiO2 electrode treated by the TiO2 LPD process was as the anode of dye-sensitized solar cell(DSSC).The effects of LPD treatment time on photovoltaic properties of DSSC were investigated.The results showed that after 25 min LPD treatment,the short circuit photocurrent density(Isc) and the conversion efficiency of the solar energy to electricity energy were increased by 13.13% and 13.95% respectively.The reason for the improvement of the photovoltaic properties was discussed. |
