合成了一种基于聚丙烯酸-聚乙二醇（PAA-PEG）杂化的新型聚合物凝胶电解质。杂化物中PEG分子量的大小决定了杂化物对液体电解质的吸收能力和聚合物凝胶电解质的离子电导率，进而影响准固态染料敏化太阳能电池的光伏性能。使用PEG分子量为20，000的杂化物，获得了液体电解质吸收率为6.9gg-1和离子电导率为5.35mScm-1的聚合物凝胶电解质。基于聚合物凝胶电解质，在AM 1.5，100 mWcm −2的照射下，获得了转换效率为5.25%的准固态染料敏化太阳能电池。
A new kind of polymer gel electrolyte based on poly(acrylic acid)–poly(ethylene glycol) (PAA-PEG) hybrid was synthesized. The factor of molecular weight of PEG in the hybrid plays an important role in determining the liquid electrolyte absorbency of the hybrid and ionic conductivity of the polymer gel electrolyte, sequentially affects the photovoltaic performance of quasi-solid-state dye-sensitized solar cells. Using the hybrid with PEG molecular weight of 20,000, a polymer gel electrolyte with liquid electrolyte absorbency of 6.9gg−1and ionic conductivity of 5.35mScm−1was obtained. Based on the polymer gel electrolyte, a quasi-solid-state dye-sensitized solar cell with conversion efficiency of 5.25% was achieved under irradiation of AM 1.5, 100mWcm−2.
