ELECTROLYTES FOR DYE-SENSITIZED SOLAR CELL USING IMIDAZOLE BASED IONIC LIQUID

摘要

PURPOSE: An imidazole-based ionic solution is provided to improve ion conductivity of electrolyte through the control of components added in the manufacture of electrolyte and the size of a linker of the ionic solution. CONSTITUTION: A method for preparing an imidazole-based polymer or oligomer type ionic solution comprises the steps of: reacting dichloromethane and 1,6-diisocyanatohexane with aminoalkylimidazole to obtain a monomer including an NCO group at a terminal group; adding chloroform and ethylene oxide compounds to the obtained compound to obtain polyethylene glycol; adding acetonitrile and alkyl iodide to the obtained compound to obtain diimidazolium iodide polyethylene.
