染料敏化太阳能电池准固态电解质 PAA-PEG 的制备 摘 要 染料敏化太阳能电池（DDSC ）以其独特的工作原理,廉价的生产成本等突出 的优点,引起了世界的广泛地关注,近年来发展极其迅速。本文制备了一种用于染料 敏化太阳能电池准固态电解 PAA-PEG 共混物。主要研究了 PEG 的含量、PEG 分 子量、有机溶剂、温度等因素对共混物吸收度和电导率的影响。结果发现 PAA-PEG 共混物中 PEG 含量为 40% 、分子量为 20000 时，对组成为 NMP:GBL=3:7 （体积比）， KI=0.5M ，I =0.05 M ，PY=0.4 M 的液态电解吸收度为 10.22g/g，电导率为 2 6130.0μs/cm 。 关键词：染料敏化太阳能电池，高分子凝胶，准固态电解质，吸收度，电导 率 I 染料敏化太阳能电池准固态电解质 PAA-PEG 的制备 Abstract The dye sensitized solar cell (DDSC) has been developed extremely rapidly by its prominent merits such as its unique working principle, the inexpensive production cost and so on. It has caused the world widely to pay attention to in recent years. In this article one kind of quasi-solid gel polymer electrolyte PAA-PEG hybrid was prepared to use for the dye sensitized solar cell. The absorbency and the conductivity of the PAA-PEG hybrid were influenced when the PEG content, PEG molecular weight, organic solvent and temperature varied. It was found using the hybrid with PEG content of 40% and its molecular weight of 20000, a polymer gel electrolyte with liquid electrolyte absorbency of 10.22g/g and ionic conductivity of 6130.0μs/cm, in which the liquid electrolyte were composed of 0.5M KI , 0.05 M I2, 0.4 M PY and the mixed organic solvents of 30 vol.% NMP and 70 vol.% GBL.
