NOVEL ORGANIC DYE AND PREPARATION THEREOF

摘要

PURPOSE: A novel organic dye for a dye-sensitized photoelectric transducer is provided to improve efficiency of solar cell through improved molar extinction coefficient, Jsc and photoelectricity conversion efficiency. CONSTITUTION: An organic dye for a dye-sensitized photoelectric transducer is represented by chemical formula 1. In chemical formula 1, o, p and q are respectively 0 or 1, wherein at least one of o, p and q is 1; An1 ~ An3 are chemical formula a and b; Ar1 ~ Ar3 are substituted or unsubstituted C6-C50 aryl group when o, p and q are 0; and Ar1 ~ Ar3 are substituted or unsubstituted C6-C50 arylene group when p or q is 1.
