| Abstract: | Polymer electrolyte membranes based on poly(ethylene oxide) (PEO) doped with TiO2 nanoparticles were synthesized by simple solution cast technique. Mesoporous TiO2 film was prepared by doctor‐blade method. The modified polymer membranes and the mesoporous films were characterized by SEM, TEM, AFM, ionic conductivity, and J‐V measurements. Dye‐sensitized solar cells (DSSC) have been fabricated in which PEO‐polymer electrolyte doped with and without nano‐TiO2 were sandwiched between porous TiO2 and counter electrodes. The DSSC with nano‐TiO2 doped polymer electrolyte shows better performance (1.68%) in comparison with pristine polymer electrolyte (1.07%), which is due to improved ionic conductivity value in polymer electrolyte system by nano‐TiO2 doping. © 2010 Wiley Periodicals, Inc.
