摘要：

Dye-sensitized solar cells have been made by using electrolytes based on a polysilsesquioxane ionic fluid. This is a nanocomposite organic-inorganic material synthesized by the sol-gel route using 1-methyl-3-[3-(trimethoxy-lambda(4)-silyl)propyl]-1H-imidazolium iodide as precursor. This compound is an imidazolium iodide derivatized with covalent attachment of a trimethoxysilane group. Condensation was obtained by formic acid solvolysis at 120 degrees C in the absence of water. The obtained materials have been characterized by IR, Si-29 NMR and conductivity measurements. Cells have been constructed by using several variants of the above electrolyte and have been characterized by current-voltage measurements.
