中文摘要:

TiO2 粘贴被混合广告准备 TiO2 (P25 ) ,乙醇,提取的水和 Ti (IV ) tetraisopropoxide (TTIP ) 的小数量,由一个热水的处理后面。在热水的处理前,一为 48 h 激动人心能阻止裂开的 TiO2 电影。TTIP 显著地把在 TiO2 粒子和它的坚持之间的化学连接提升到底层, 6 mol% 的 TTIP 数量是合适的。紫外照耀能移开一些杂质并且与 2 h 的一最佳的时间从 TiO2 电影流水。传播电子显微镜学, X 光检查衍射,扫描电子显微镜学和光电的测试被描绘并且测量。电线走火当前的密度,开电路的电压,充满因素和光电的变换效率因为制作灵活敏化染料的太阳能电池是 7.20 妈 cm2, 0.769 V, 0.686 和 3.84% ,分别地在有 100 mW cm2 的一盏模仿的太阳的灯的照耀下面。

英文摘要:

A TiO2 paste was prepared by mixing commercial TiO2 (P25), ethanol, distilled water and a small amount of Ti (IV) tetraisopropoxide (TTIP), following by a hydrothermal treatment. Before hydrothermal treatment, a stirring for 48 h can prevent cracking TiO2 films. TTIP significantly promote the chemical connection between TiO2 particles and its adherence to the substrate, the TTIP amount of 6 mol% is suitable. UV irradiation can remove some impurities and water from the TiO2 film with an optimal time of 2 h. Transmission electron microscopy, X-ray diffraction, scanning electron microscopy and photovoltaic tests are characterized and measured. Short-circuit current density, open-circuit voltage, fill factor and photoelectric conversion efficiencies for the fabricated flexible dye-sensitized solar cell are 7.20 mA cm-2, 0.769 V, 0.686 and 3.84%, respectively, under irradiation with a simulated solar light of 100 mW cm-2.
