摘要: Abstract Two latent chemical cross-linked precursors: (1) oligo-organophosphazene with propionitrile and iodo-(ethylene oxide- co -propylene oxide) (2) oligo-organosiloxane grafting oligo-ethylene oxide propylene dimethylamine are synthesized to form all-solid-state polymer electrolyte for dye-sensitized solar cells employing in situ quaterization reaction. This novel shows about 6.79 × 10 −7 cm 2 s −1 of the apparent diffusion coefficient triiodide. The disintegrating temperature 181 °C demonstrates good thermal stability solid-state electrolyte. Proper amount 7 nm SiO modified 3-triethoxysilylpropyl oligo(oxyethylene- -oxypropylene) monomethyl urethane is added photocurrent conversion efficiency reaches 2.66% compared that 1.81% no additive.
