摘要

Quasi-solid-state electrolytes were fabricated with mesoporous silica SBA-15 as a framework material. Ionic conductivity measurements revealed that SBA-15 can enhance the conductivity of the quasi-solid-state electrolyte.The diffusion coefficients of polyiodide ions such as I-3 and I-5 which were confirmed by Raman spectroscopic measurement, were about twice larger than that of I-. The optimized photoenergy conversion efficiency of dye-sensitized solar cells (DSSC) with the quasi-solid-state electrolyte was 4.3% under AM 1.5 irradiation at 75 mW·cm-2 light intensity.
