Abstract: A new kind of carboxyl group-functionalized silica nanoparticles were synthesized and employed as framework to form “soggy sand” electrolyte for dye-sensitized solar cells. The property of this electrolyte has been evaluated by studying the effect of the carboxyl group-functionalized silica nanoparticles content on the performance of dye-sensitized solar cells. The cells based on electrolyte containing the carboxyl group-functionalized silica nanoparticles show better performance owing to the increased short-circuit photocurrent than that of the liquid device and yield the energy conversion efficiency of 7.1% under AM 1.5 illumination at 100mVcm−2 when the content of the carboxyl group-functionalized silica is 15wt.%.
