|
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 TiO_2 thin film,this experiment use liquid phase deposition method to fabricate thin film on the condition of constant temperature and variable temperature. The FTO 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 TiO_2 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 FTO reached5. 71%,and on the same conditions the efficiency of cells based on PET-ITO is 4. 07%.
