摘要
在TiO2粉体中加入不同量的聚乙二醇400、OP乳化剂和乙酰丙酮,经球磨得到TiO2浆料,采用丝网印刷的工艺方法在基底上制备了多孔TiO2薄膜阳极,组装成DSSC。采用SEM、XRD和电化学工作站进行了表征及测试;利用正交实验探讨了浆料中聚乙二醇400、OP乳化剂、乙酰丙酮的量和球磨时间对DSSC光电性能的影响。研究结果表明,浆料的最佳配方是聚乙二醇400为0.4mL、OP乳化剂为0.02mL、乙酰丙酮为0.6mL和球磨时间为4h,由此可使制备的DSSC光电转化效率(η)达到3.44%。
The TiO2 paste was obtained by ball milling, with varying amounts of PEG400,OP emulsifier and aeetylacetone. Then the screen-printed technique was adopted to fabricate porous TiO2 film anode on substrate, and DSSC was assembled by TiO2 film anode. The experimental samples were investigated and measured by means of SEM, XRD and electrochemical metho＆ The effect of PEG400, OP emulsification, acetylacetone and ball milling time on DSSC properties was discussed by ortbogonal experiment. The results indicate that the optimal component are PEG400 of 0. 4mL, OP emulsifier of 0. 02mL, acetylacetone of 0. 6mL and the ball milling time of 4h. The value of overall energy conversion efficiency 71 of DSSC of the optimal assembled is 3. 44%.
