ORGANIC METAL DYE INCLUDING A CONDENSED HETEROCYCLIC DERIVATIVE HAVING HIGH OPTICAL ABSORBTION RATE AND ABSORPTION BAND IN A LONG WAVELENGTH, A PHOTOELECTRIC ELEMENT USING THE SAME, AND A DYE-SENSITIZED SOLAR CELL

摘要

PURPOSE: An organic metal dye is provided to improve optical absorption rate and photoelectric transformation efficiency since a molar extinction coefficient increases and a maximum absorption wavelength moves to a long wavelength. ;CONSTITUTION: An organic metal dye is represented by chemical formula. In chemical formula, Cy1 and Cy2 are a pyridine group or C5-40 nitrogen-containing condensed heteroaryl group; M is metal selected from Ru, Os and Fe; L1 and L2 are independently selected from H2O, -Cl, -I, -CN, -NCO and -NCSe; A1, A2, B1 and B2 are independently substituted or unsubstituted alkyl, substituted or unsubstituted alkenyl, substituted or unsubstituted alkynyl, substituted or unsubstituted aryl, and substituted or unsubstituted heteroaryl; and m, n, o and p are an integer of 1-20.;COPYRIGHT KIPO 2011
