DYE COMPOND FOR DYE SENSITIZED SOLA CELL AND SOLA CELL COMPRISING IT

摘要

PURPOSE: An organic dye compound reduces the recombination rate with electrolyte, has high electron flowability as the planarity in a molecule is expanded, and maximizes photoelectric conversion efficiency at high Voc. CONSTITUTION: An organic dye compound is represented by chemical formula 1. In chemical formula 1, X is selected from halogen, halogen-substituted alkyl, alkenyl, and alkynyl group; Y is non-existent or is S or O; Z is a substituted or unsubstituted C1-30 alkyl, a substituted or unsubstituted C1-30 alkenyl, a substituted or unsubstituted polyvinyl, a substituted or unsubstituted C6-60 aromatic hydrocarbon, a substituted or unsubstituted C2-60 heterocycle, and a substituted or unsubstituted amine; B is non-existent or is a substituted or unsubstituted C6-60 aromatic hydrocarbon or a substituted or unsubstituted C2-60 hetero ring; and A is a substituted or unsubstituted C1-30 alkyl, a substituted or unsubstituted C2-30 alkenyl, a substituted or unsubstitutedC2-30 alkynyl, a substituted or unsubstituted C6-60 aromatic hydrocarbon, and a substituted or unsubstituted C2-60 hetero ring.
