This work deals the preparation of a new polymer gel electrolyte using an efficient poly (acrylonitrile)-co-poly (butyl acrylate) (PAN-co-PBA) for solid-state DSSCs. Prepared PAN-co-PBA exhibited the superabsorbent behavior as seen the carboxylate group in copolymer. An excellent gelation with iodide couple and high ionic conductivity of 3.86 mS/cm was recorded for PAN-co-PBA gel electrolyte. Fabricated DSSC with 7% PAN-co-PBA attained the highest overall conversion efficiency of ∼5.23% along with high JSC=13.16 mA/cm2, VOC=0.646 V and FF=0.62. Improved DSSC performance might be related to excellent gelation and high ionic conductivity of PAN-co-PBA gel electrolyte, resulting in improving interfacial contact and pore filling.

基于聚丙烯酸丁酯(PBA)-共聚丙烯腈(PAN)的稳定型凝胶电解质,用于固态染料敏化太阳能电池
这项工作涉及使用固态DSSC的高效聚(丙烯腈)-共聚(丙烯酸丁酯)(PAN-co-PBA)制备新的聚合物凝胶电解质。所制备的PAN-co-PBA表现出超吸收行为,如在共聚物中的羧酸根基团所见。对于PAN-co-PBA凝胶电解质,记录了极好的碘化物凝胶化和3.86 mS / cm的高离子电导率。制造的DSSC用7%PAN-CO-PBA获得的~5.23%的最高总转换效率高Ĵ沿着SC =13.16毫安/厘米2,V OC = 0.646 V和FF = 0.62。DSSC性能的改善可能与PAN-co-PBA凝胶电解质的优异凝胶化和高离子电导率有关,从而改善了界面接触和孔填充。
