摘　　要：以AS树脂作为聚合物凝胶电解质基体，乙腈和四氢呋喃作为混合有机溶剂制备准固态染料敏化太阳电池。经过各个组成的优化，聚合物凝胶电解质电导率（30℃）达到5．11mS／cm，准固态染料敏化太阳电池的光电转换效率在100mW／cm^2光强下达2．56％：温度对聚合物凝胶电解质的电导率的影响；通过在聚合物凝胶电解质中加入纳米聚吡硌添加剂，准固态染料敏化太阳电池的光电转换效率在100mW／cm^2光强下提高到3．23％。A polymer gel electrolyte with ionic conductivity of 5.11 mS/cm was prepared by using poly （acrylonitrile-co- styrene） as polymer matrix, acetonitrile and tetrahydrofuran as binary organic mixture solvent, NaI ＋ I2 as electrolyte, and polypyrrole nanoparticle as additives. The influence of temperature on the ionic conductivity and photoelectronic properties of dye-sensitized solar cell were investigated. Based on the polymer gel electrolyte with the optimized conditions, a quasi-solid -state dye-sensitized solar cell was fabricated and its overall energy conversion efficiency of light-to-electricity of 3.23 % was achieved under irradiation of 100 mW/cm^2.
