The cross-linked poly(ethylene glycol) (PEG-1000) was prepared by condensation reaction with tetraethoxysilane (TEOS). Using the cross-linked PEG-1000 as polymer host, 0.60 M KI and 0.06 M I(2) as ionic conductors, an ionic conductivity of the polymer electrolyte was achieved 3.12 mS cm(-1). Based on the optimized crosslinked PEG electrolyte, the best result of the quasi-solid state dye-sensitized solar cell (QS-DSSC) was the short-circuit photocurrent of 11.87 mA cm(-2), the open-circuit photovoltage of 706 mV, the fill factor of 0.593 and the light-to-electricity conversion efficiency of 4.97% at 100 mW cm(-2) (AM 1.5).
