Application of the Novel Porous Gel Electrolyte in Flexible Quasi-Solid-State Dye-Sensitized Solar Cell

制备了一种新型多孔聚丙烯酸/十六烷基三甲基溴化铵聚吡咯凝胶电解质,并将其应用于柔性基染料敏化太阳电池(DSSC)。通过扫描电镜表征、热重分析测试、电化学性能测试和柔性电池光电性能测试等手段,分析了凝胶电解质对柔性基DSSC的光电性能影响。研究结果表明:随着聚吡咯的引入,提高凝胶电解质导电性以及催化电解质中的I-/I3-离子电对等性能,最终在100mW/cm2[大气质量(AM)1.5]光照条件下,测得基于该准固态凝胶电解质的柔性基DSSC光电转换效率达1.28%。

A novel gel polymer electrolyte based on poly（acrylic acid-g-CTAB）-polypyrrole is prepared. Based on the gel electrolyte, a flexible quasi-solid-state dye-sensitized solar cell （DSSC） is fabricated by using a low-temperature filming technique. The researches by scanning electron microscopy, thermal degradation analysis and cyclic voltammetry show the effect of the gel polymer electrolyte on flexible DSSC. Owing to high conductivity and the catalytic function of polypyrrole for I-/I3- redox reaction for the gel electrolyte, the flexible quasi-solidstatedye- sensitized solar cell shows a light-to-electric energy conversion efficiency of 1. 28%, under simulated solar light irradiation with intensity of 100 mW/cm2 [air mass （AM） 1.5].
