染料敏化太阳能电池准固态电解质相比液体电解质,具有机械性能好,电池稳定性高,能有效防止电解质泄漏,使用寿命延长等优点，已成为电池的研究重点之一。本项目把低聚物应用到准固态电解质中，制备低聚物准固态电解质，利用低聚物分子直径小的特点，提高电解质在多孔膜中的渗透效果。同时，采用添加增塑剂、交联剂和无机盐粒子方法等对电解质进行改性，分析电解质的离子导电机理，提高其电导率。其次，制备新型氧化还原电对低聚物准固态电解质，以及有机空穴传输材料/氧化还原电对复合低聚物电解质体系，探讨新型电解质体系的载流子传输机理。希望通过研究，获得导电性能好的低聚物准固态电解质，阐明电解质的导电机理，进一步提高染料敏化纳米晶太阳能电池的光电转换效率。

Quasi-solid state dye sensitized solar cells is well-known for its high mechanical strength and good stability without leakage. It is a hot spot for study. In this project, we will use oligomer to prepare quasi solid state electrolyte to improve the penetration into the mesoporous photoanode. At the same time, we will study the ionic conductivity of the quasi solid state electrolyte by adding plasticizer, cross-linker and inorganic nanoparticles to the oligomer electrolyte. Moreover, by utilizing the new redox couple and the hole transport materials into the quasi solid state electrolyte, the performance of the dye sensitized solar cell with the electrolyte can be improved. We will study the ionic conductivity of the new oligomer quasi solid state electrolyte and its usage in the dye sensitized solar cells. By these effort, the performance of the quasi-solid state dye sensitized solar cells canbe largely improved.
