摘要:

染料敏化太陽電池（DSSC），因廉價、清潔、高效等優點而備受關注和研究。電解質作為DSSC的重要組成部分，對電池的穩定性能及內部電子輸運和染料再生等方面有重要的影響。目前，基于液態電解質的DSSC的光電轉換效率已突破14%，但液態電解質中有機溶劑易揮發，造成電池封裝困難和使用壽命縮短等問題，限制了DSSC的發展。準固態電解質的引入，在保證電池具有較高效率的同時改善了DSSC的長期穩定性，并將利于DSSC大規模的商業化生產。對液態電解質、固態電解質以及準固態電解質的性能、優點及存在的問題進行了概述；并從可逆/不可逆的角度出發，詳細評述了準固態電解質在DSSC中的研究進展，分析了準固態電解質在DSSC中的發展趨勢。

Abstract:

Dye�瞫ensitized 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�瞓ased 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�瞭erm durability are still one of the key issues in the commercial application of liquid electrolyte based DSSCs. To solve these issues, the quasi�瞫olid�瞫tate electrolytes as efficient solutions are developed. In this review, the performance, advantages and disadvantages of liquid electrolyte, quasi�瞫olid�瞫tate electrolyte and solid�瞫tate electrolyte are summarized. With special focus on the performance of the quasi�瞫olid�瞫tate electrolytes in DSSCs, the applications of reversibility/irreversibility electrolytes have been reviewed and discussed. Furthermore, the benefits, challenges and potential utility of quasi�瞫olid�瞫tate electrolytes for use in DSSCs are also assessed.
