dc.descriptionThe addition of the plasticizer poly(ethylene glycol)methyl ether to the polymer electrolyte based on poly(epichlorohydrin-co-ethylene oxide), NaI and I-2 increased the ionic conductivity by one order of magnitude (1.7 x 10(-4) S cm(-1)) without compromising its electrochemical, thermal and dimensional stabilities. The plasticized polymer electrolyte presented an estimated diffusion coefficient of 2 x 10(-6) cm(-2) s(-1), ca. five times higher than the diffusion coefficient estimated for the polymer electrolyte without plasticizer. Solid-state dye-sensitized TiO2 solar cells (1 cm(2)) were assembled with the plasticized polymer electrolyte and presented an open circuit potential of 0.64 V, short-circuit current of 0.60 mA cm(-2) and an energy conversion efficiency of 1.75% under light intensity of 10 mW cm(-2). This efficiency remained unchanged for 30 days, showing that cell efficiency and stability can be improved using a plasticized polymer electrolyte. (c) 2005 Elsevier B.V. All rights reserved.
