ORGANIC DYE WITH EXCELLENT MOLAR EXTINCTION COEFFICIENT, JSC AND PHOTOELECTRICITY CONVERSION EFFICIENCY FOR A DYE-SENSITIZED PHOTOELECTRIC TRANSDUCER AND A PREPARATION METHOD THEREOF

摘要

PURPOSE: A novel organic dye for a dye-sensitized photoelectric transducer is provided to improve efficiency of solar cell by showing improved molar extinction coefficient, Jsc and photoelectricity conversion efficiency compared with conventional dye.;CONSTITUTION: A novel organic dye for a dye-sensitized photoelectric transducer is represented by chemical formula 1 or 2. In chemical formula 1 or 2, A is chemical formula a, wherein Ar1 ~ Ar3 are substituted or unsubstituted C6-C50 aryl group or can form a hetero ring with N by connecting at least two of A1 ~ Ar3; R1 and R2 are respectively C1-12 alkyl, substituted or unsubstituted C6-30 aryl, and substituted or unsubstituted C6-20 heteroaryl.;COPYRIGHT KIPO 2011
