液相沉积低温制备染料敏化太阳能电池光阳极及表征

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TiO2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;.

Preparation and Characterization of Dye-sensitized Solar Cells by Liquid Phase Deposition Method at Low Temperature

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 reached 5.71;, and on the same conditions the efficiency of cells based on PET-ITO is 4.07;.
