NOVEL ORGANIC DYE AND PREPARATION THEREOF

摘要

PURPOSE: A novel organic dye in which a thiophene- or dihydrothiophene-based used is introduced to an interconnection spacer and a method for preparing the same are provided to ensure excellent molar extinction coefficient, Jsc(short circuit photocurrent density) and photoelectric conversion efficiency compared with conventional dyes and to lower a dye synthesis cost by enabling the purification without inexpensive columns. CONSTITUTION: A novel organic dye is represented by chemical formulas 1-4. In chemical formulas 1-4, Ar is substitutedor unsubstituted C6-12 aryl; R1 - R4 are independently hydrogen, C1-12 alkyl or substituted or unsubstituted C6-12 aryl; and n is an integer of 1 - 5. A dye-sensitized photoelectric conversion device comprises oxide semiconductor microparticles in which the organic dye is supported. A dye-sensitized solar cell includes the dye-sensitized photoelectric conversion device.
