通过简单方法合成了一种新型有机碘盐N-甲基吡啶碘,以苯乙烯-丙烯腈共聚物(AS树脂)为聚合物凝胶电解质基体,丙烯碳酸酯及乙烯碳酸酯双组分有机溶剂为液相,制备了含有机碘盐(N-甲基吡啶碘)和无机碘盐(NaI)的AS树脂基聚合物凝胶电解质,比较了两种碘盐对聚合物凝胶电解质导电性能及染料敏化纳米晶太阳电池光电性能的影响,发现含有机碘盐的聚合物凝胶电解质具有较高的电导率,所制备的DSSC光电性能也较好。
A novel organic iodide salt (N-methyl pyridine iodide) was synthesized, polymer gel electrolytes with poly(acrylonitrile-co-styrene) polymer matrix, ethylene carbonate and propylene carbonate binary mixed solvents and organic iodide salt (N-methyl pyridine iodide ) or inorganic iodide salt (NaI) were prepared. It is found that polymer gel electrolyte containing N-methyl pyridine iodide has higher ionic conductivity than that of inorganic iodide salt. The DSSC with polymer gel electrolyte containing N-methyl pyridine iodide shows higher photovoltaic performance than that of inorganic iodide salt.
