| 摘 要： | 用溶胶-凝胶法在导电玻璃上制备不同成膜方式和层厚的TiO2致密膜阻挡层,采用水热法制备外层多孔TiO2薄膜。用场发射扫描电镜(FE-SEM)和紫外-可见分光光度计分析阻挡层成膜方式和层厚对复合光阳极薄膜的表面形貌和吸光度的影响,并研究其对应的DSSC的电学性能。结果表明:阻挡层经层层烧结,复合光阳极具有较疏松的表面形貌,吸光度和DSSC的电学性能最佳;阻挡层的层厚对复合膜的吸光度和DSSC的电学性能影响不大,但层数为8层时具有最好的吸光度和电学性能。

| Abstract: | The dense TiO2 blocking layer with different thickness was prepared on conductive glass by sol-gel method,and the outer TiO2 porous film was prepared by hydrothermal method.The influence of preparation methods and the thickness of dense barrier films on surface morphology and absorbance were analyzed by field emission scanning electron microscope(FE-SEM) and UV-vis spectrophotometer.In addition,the electrical properties of the DSSC were studied.The results indicate that,when the barrier layer is prepared by sintering each layer,the composite photo-anode possesses a relatively loose surface morphology,and therefore has a maximum absorbance.At the same time,the DSSC presents the best electrical properties.The thickness of the barrier layer has little effect on absorbance and electrical properties,but when the number of barrier layer is 8,the photo-anode has the maximum absorbance and DSSC has the best electrical properties. |
