Properties of poly(4-vinylpyridine-co-acrylonitrile) gel electrolytes

采用自由基溶液聚合法合成出P(4-VP-co-AN),通过与交联剂发生化学交联反应固化液体电解质,制得凝胶电解质,并将其应用于染料敏化太阳能电池。当AN为聚合物质量分数为25%时,制备的凝胶电解质DSSCs具有较好的光电性能;同时,交联剂含量为P(4-VP-co-AN)质量的1.5%时,制备的凝胶电解质DSSCs光电性能最佳,与纯液体电解质DSSCs相比,其光电转换效率和最大输出功率分别达到液体电解质电池的77.38%和78.57%。

An electrolyte gel, P （4-VP-co-AN）, is synthesized by radical solution polymerization. The gel electrolytes containing liquid-electrolyte are prepared by chemical cross-linking reaction of P （4-VP-co-AN） with the gelator,and aiming to be used in dye-sensitized solar cells. The DSSCs with gel polymer electrolytes containing a 25% AN and the DSSCs with the gel electrolyte precursor containing 1.5% of gelator both exhibite optimal photo-electric behaviors. The photo-electric conversion efficiency and peak output power of the quasi-solid state dye-sensitized solar cells respectively can reach 77. 38% and 78. 57% ,respectively,compared with that of the liquid electrolyte DSSCs.
