摘要:: 染料敏化太阳电池（DSSC），因廉价、清洁、高效等优点而备受关注和研究。电解质作为DSSC的重要组成部分，对电池的稳定性能及内部电子输运和染料再生等方面有重要的影响。目前，基于液态电解质的DSSC的光电转换效率已突破14%，但液态电解质中有机溶剂易挥发，造成电池封装困难和使用寿命缩短等问题，限制了DSSC的发展。准固态电解质的引入，在保证电池具有较高效率的同时改善了DSSC的长期稳定性，并将利于DSSC大规模的商业化生产。对液态电解质、固态电解质以及准固态电解质的性能、优点及存在的问题进行了概述；并从可逆/不可逆的角度出发，详细评述了准固态电解质在DSSC中的研究进展，分析了准固态电解质在DSSC中的发展趋势。

Abstract:: Dyesensitized solar cells (DSSC) have received significant attention on account of their low cost, cleanliness, and high photoelectric conversion efficiency. As an important component of DSSC, electrolyte has a great influence on the stability, charge transport and dye regeneration of DSSC. At present, the high photovoltaic conversion efficiency from liquid electrolytebased DSSC has exceeded 14%, but they are suffering from some questions, such as the evaporation of the organic solvents, difficult sealing and short life span of devices. Therefore, the device stability and longterm durability are still one of the key issues in the commercial application of liquid electrolyte based DSSCs. To solve these issues, the quasisolidstate electrolytes as efficient solutions are developed. In this review, the performance, advantages and disadvantages of liquid electrolyte, quasisolidstate electrolyte and solidstate electrolyte are summarized. With special focus on the performance of the quasisolidstate electrolytes in DSSCs, the applications of reversibility/irreversibility electrolytes have been reviewed and discussed. Furthermore, the benefits, challenges and potential utility of quasisolidstate electrolytes for use in DSSCs are also assessed.
