准固态电解质在染料敏化太阳电池中的应用和发展

染料敏化太阳电池（DSCs，dye-sensitized solar cells）近年已经成为一个研究热点。而电解质对电池的效率和稳定性起着重要的作用。目前常用的乙腈基液态电解质存在封装和泄漏的问题，尤其是在高温下。将准固态聚合物电解质应用到 DSCs 中可以有效解决应用液态电解质遇到的封装难稳定性差等问题，因而近年来，对准固态电解质的研究引起了广泛关注。本文综述了准固态电解质的研究进展，根据固化方式的不同将准固态电解质分为：有机小分子凝胶电解质、聚合物凝胶电解质和添加纳米粒子的凝胶电解质；讨论了每种准固态电解质的特点及存在的问题；最后对准固态电解质的发展进行展望。

Application and Development of Quasi-Solid Electrolytes in Dye-sensitized Solar Cells

Dye-sensitized solar cells (DSCs) have become a research hotspot. On the DSCs efficiency and stability, electrolytes play an important role. Common acetonitrile based liquid electrolytes are difficultly encapsulated and easily leakage, especially in high temperature. To adopt quasi-solid electrolytes (QSEs) can solve above problem in DSCs, therefore QSEs have been attracting widespread interest. According to curing method, QSEs are divided into micro-molecular organic gelator, polymer gelator and nano-powder gelator. This paper reviewed the lastest research progress of QSEs and the feature and problem of each kind of QSEs are particularly discussed. Finally. the prospects of the future development of QSEs are presented.
