摘要 染料敏化太阳能电池(DSCs)具有成本低廉、制作工艺简单、光电转换效率较高等优点,在新一代薄膜太阳能电池中,被认为是最具市场潜力的新型太阳能电池之一。电解质在染料敏化太阳能电池中起到桥梁作用,担负着还原染料、输运载流子完成电池内部循环的作用。液态电解质虽然效率高,但是易挥发和泄露,对电池的稳定性和寿命有很大的影响。因此,设计、制备高性能的固态电解质是DSCs电池发展的必然趋势,并且对电池实用化和产业化具有重要意义。本文介绍了DSCs电池的基本结构和工作原理,结合本实验室在DSCs电池方面的工作,着重阐述固态电解质的研究现状及发展趋势。 Dye-sensitized solar cells (DSCs) are promising alternative to conventional Si-based solar cells due to their low cost, easy fabrication and relatively high conversion efficiency. In the DSC, the electrolyte plays an important role in the regeneration of dye molecules and the charge transportation. Although the DSCs based on the liquid electrolyte can present much better photovoltaic performance, the disadvantages of the liquid electrolytes (i. e. volatility and easy leakage) are supposed to reduce the long-term stability. Therefore, the development of (quasi) solid-state electrolytes is necessary and imperative. In this paper, the recent progress on the solid-state electrolytes and the prospects are given.
