摘要/Abstract

摘要：

采用小分子胶凝剂四(十二烷基)氯化铵胶凝3-甲氧基丙腈基液体电解质制备了凝胶电解质, 并组装成准固态染料敏化太阳电池. 差示扫描量热测试结果表明, 凝胶电解质的溶液-凝胶转变温度(TSG)为74 ℃. 分析了凝胶电解质中I-3/I-电对的表观扩散系数低于液体电解质的原因, 同时结合电化学阻抗技术考察了电池内部二氧化钛多孔薄膜电极/电解质界面处的暗反应, 分析了凝胶化对电池光伏性能的影响. 老化实验结果表明, 凝胶电池的稳定性明显优于液体电池.

Abstract:

Quasi-solid-state dye-sensitized solar cell(DSC) was fabricated using tetradodecylammonium chloride as a low molecular mass gelator to form gel electrolyte. The differential scanning calorimetry measurement shows the solution-to-gel transition temperature(T_SG) of the gel is 74 ℃. It is also found that the gelation decreased the apparent diffusion coefficient(D_app) values of triiodide and iodide ions in electrolyte. The influence of gelation on the charge recombination at the dyed TiO2 mesoscopic electrode/electrolyte interface was investigated by adopting electrochemical impedance spectroscopy(EIS) technology. The result showed that the gelation increased the dark reaction at the dyed TiO₂ mesoscopic electrode/electrolyte interface. The result of the accelerated aging test showed that the gel electrolyte based DSC exhibited much better stability than the device based on the liquid electrolyte.
