NOVEL ORGANIC DYE AND PREPARATION THEREOF

摘要

PURPOSE: An organic dye is provided to improve a molar extinction coefficient, Jsc(short circuit photocurrent density) and photoelectric conversion efficiency as compared with those of conventional dyes, thereby enhancing the efficiency of the solar cell. CONSTITUTION: An organic dye comprises: a specific aliphatic compound as an electron donor; and a thiopheneic or dehydrothiopheneic unit in an intermediate connecting part(spacer). In chemical formulas 1 - 4, Ar is substituted or 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.
