摘要/Abstract

摘要： 采用溶胶-凝胶水热法制备了锐钛矿型纳米晶TiO₂薄膜电极,在乙二醇碳酸酯(EC)/1,2-丙二醇碳酸酯(PC)电解液体系中,研究了I₂和KI含量对电极光电性能的影响,发现随着电解液中I₂含量的增加,电池的短路光电流呈现先增加后减小的趋势,但光电流增加和减少的幅度并不大,同时体系的暗电流不断增加,光电压不断下降;随着电解液中KI含量的增加,电池的短路光电流也不断增加,当KI的含量大于0.2 mol/L时,电池的短路光电流的增加的趋势减缓.并对电解液中I₂和KI含量对电池光电性能影响的原因进行了初步的探讨.

Abstract: Nano-crystalline TiO₂ film was prepared by combining the sol-gel and hydrothermal process.The crystal type of the TiO₂ film was identified as anatase.In the ethylene carbonate (EC)/ propylene carbonate (PC) electrolyte system,the effect of the content of I₂ and KI was studied.The results showed that the photocurrent increased at first and decreased subsequently with the increasing of I₂ content in the electrolyte,but the changes were not evident.At the same time,the dark current was elevated,and as a result,the open-circuit photovoltage (V_OC) was reduced.When the electrolyte system contained few KI,the short-circuit photocurrent could be enhanced by the addition of more KI in the electrolyte.When the content of KI was higher than 0.2 mol/L,this change slowed down.The mechanism of these effects had also been explored.

Key words: dye-sensitized solar cell, TiO₂ film electrode, electrolyte system
