| 摘 要： | 用溶胶-凝胶法在染料敏化太阳能电池的FTO导电玻璃与多孔薄膜之间制备了一层TiO2致密膜,采用AFM、XRD、UV-Vis以及接触角测定仪等对其进行表征。结果表明,制备的薄膜结构致密、透明,晶粒细小均匀;水接触角从FTO表面的54.425°下降到致密膜表面的33.763°,有利印刷浆料润湿结合;对比实验证实了TiO2致密膜的引入,隔离了液体电解质与FTO导电玻璃的直接接触,减小电池的暗电流,电池的电流密度及光电转化效率分别提高了17.7%和22.4%。

| Abstract: | The TiO_2 density film was prepared by the sol-gel method between the Fluorine Tin Oxide(FTO) Glass and multiporous film in the DSSC and characterized by AFM,XRD,UV-Vis and contact angle measuring instrument.The results showed that the grain size of the TiO_2 was fine,the film was dense and transparent,the water contact angle decreased from 54.425° to 33.763° on FTO.Compared to the DSSC with no coating TiO_2 density film,the introduction of the density film avoided the contact of electrolyte with FTO directly which decreased the dark current,the photoelectric conversion efficiency and short-circuit photocurrent increased by 17.7%,22.4%,respectively. |
