A UV-prepared linear polymer electrolyte membrane for dye-sensitized solar cells

The effects of LiClO4 and LiFS3SO3 on poly(glycidyl methacrylate)-based solid polymer electrolyte and its photoelectrochemical performance in a dye sensitized solar cell consisting of FTO/TiO2-dye/P(GMA)-LiClO4-EC/Pt were investigated. The electrochemical stability of films was studied by cyclic voltammetry (CV). The highest ionic conductivities obtained were 4.2 x 10(-5) and 3.7 x 10(-6) S cm(-1) for the film containing 30 wt% LiClO4 and 25 wt% LiCF3SO3, respectively. The polymer electrolytes showed electrochemical stability windows up to 3 V and 2.8 V for LiClO4 and LiCF3SO3, respectively. The assembled dye-sensitized solar cell showed a sunlight conversion efficiency of 0.679% (J(sc) = 3 mA cm(-2),V-oc = 0.48 V and FF=0.47), under light intensity of 100 mW cm(-2).
