NOVEL UREA-CONTAINING IMIDAZOLIUM IODIDE COMPOUND, PREPARATION METHOD THEREOF AND ELECTROLYTE FOR DYE-SENSITIVED SOLAR CELL

摘要

PURPOSE: An electrolyte containing a novel urea-containing imidazolium iodide compound, which exists in a quasi-solid(gel) state with large viscosity is provided to ensure excellent stability when being used for an electrolyte of a dye-sensitized solar cell, and to ensure transport capacity of an anionic material in a cell. CONSTITUTION: A urea-containing imidazolium iodide is denoted by chemical formula 1 or 2. A method for preparing the compound of chemical formula 1 comprises: a step of reacting iminopropyl imidazole of chemical formula 3 with R_2-NCO of chemical formula 4 to prepare a compound of chemical formula 5; and a step of reacting the compound of chemical formula 5 with R1-I of chemical formula 6. An electrolyte for a dye-sensitized solar cell contains the urea-containing imidazolium iodide of chemical formula 1 or 2.
