摘要
本研究采用液相沉积法在恒温与变温两种条件下进行沉积,选用FTO导电玻璃与柔性PET-ITO作为基底。由XRD结果可知产物均为锐钛矿相二氧化钛,80℃条件下结晶性更好;SEM测试结果表明Ti O_2薄膜层为多孔结构。变温条件制备的电池效率最高,而60℃恒温条件制备的电池效率略高于80℃。FTO作为基底在梯度温度下制备组装的电池效率达到5.71%,相同条件下制备的柔性基底组装的电池效率为4.07%。
In order to explore the new method for preparing the TiO2 thin film, this experiment use liquid phase deposition method to fabricate thin film on the condition of constant temperature and variable temperature. The FFO conductive glass and flexible PET-ITO were selected to be compared. XRD results show that the products are anatase phase titanium dioxide, the conditionof 80 ℃ in favour of better crystallinity. SEM results show the porous structure of TiO2 film layer. Theefficiency prepared on the condition of variable temperature is the highest, and the sample prepared in 60℃ has higher efficiency than it prepared in 80℃. The efficiency of cells prepared at gradient temperature based on TFO reached 5.71% , and on the same conditions the efficiency of cells based on PET-ITO is 4.07%.
