摘　　要：染料敏化太阳能电池是近十几年来发展起来的新型高效率、低成本电池。电解质是关系到该电池稳定性的重要材料。介绍了染料敏化太阳能电池电解质的分类,讨论了准固态电解质和固态电解质的优缺点及其研究进展。使用传统的液态电解质获得的光电转换效率较高,但稳定性受到一定的影响,使用准固态电解质和固态电解质制备的染料敏化太阳能电池,稳定性有了较大的提高。重点讨论了准固态电解质以及无机p型半导体材料、有机p型半导体材料和导电高聚物等几种主要的固态电解质的特点和相应的电池稳定性。Dye-sensitized Solar Cells （DSCs）, as a new type of solar cells developed over the past decade, are regarded as low-cost and high-efficiency solar cells. The electrolyte is an important material of the DSCs, which relates closely to the cell＇s stability. In this paper, the electrolytes of dye-sensitized solar cells are discussed, including the advantage and disadvantage of quasi-solid state electrolyte and solid state electrolyte, and the recent progress. At present, high energy conversion efficiency of DSCs is achieved with conventional liquid electrolytes, which involve a serious problem of stability. With the quasi-solid state electrolyte and solid state electrolyte the stability of DSCs may be remarkably improved. The characteristics of quasi-solid state electrolyte and solid state electrolyte, including inorganic p-type semiconductors, organic p-type semiconductors and polymer electrolytes, are analyzed, together with the stability of the cells.
