Gelation of ionic liquid-based electrolyte with ordered mesoporous silica particles for quasi-solid-state dye-sensitized solar cells

摘要：

Ordered mesoporous silica with uniform pore size was prepared by using Pluronic P123 as the structure-directing agent. Their characteristics were analysized by TEM and a N2 adsorption system. Ionic liquid-based gel electrolyte was fabricated by using ordered mesoporous silica as the framework materials to solidify ionic liquid electrolyte. The diffusion coefficient of I3 - in gelelectrolyte is higher than that in ionic liquid electrolyte due to the formation of favorable channel for I3- diffusion. The optimized overall conversion efficiency of dye-sensitized solar cells with ionic liquid-based gel electrolyte was 5.22％ under irradiation of 60 mW cm-2.
