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 cross‐linked 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). © 2010 Wiley Periodicals, Inc.
