Abstract

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.
