Abstract :
Gel polymer electrolyte based on poly(acrylonitrile-co-styrene)/NaI+I2 and binary solvent mixture was prepared. When
the system contains 0.5 M NaI and 0.05 M I2, the maximum ionic conductivity (at 30 C) of 2.37 mS cm 1 was achieved.
Based on a gel polymer electrolyte with 0.5 M NaI, 0.05 M I2 and 0.5 M 4-tert-butylpyridine, a quasi-solid state dye-sensitized
solar cell was fabricated and its overall energy conversion efficiency of light-to-electricity of 2.75% was achieved
under irradiation of 60 mW cm 2.
