PORPHYRIN-BASED PHOTOSENSITIZER DYES FOR DYE-SENSITIZED SOLAR CELLS

Abstract

This invention relates to photosensitizer dyes for dye-sensitized solar cells. The photosensitizer dyes are porphyrin-based zinc complexes represented by the following general formulae (100) and (200).wherein A is represented by one of the following formulae (111)˜(118),wherein Z1˜Z10 independently represent a hydrogen atom (H), lithium (Li), sodium (Na), or tetra-alkyl ammonium group (as represented by the following general formula (120)),wherein X1˜X4 independently represent CmH2m+1 (m=1˜6), and B, C, D, and E independently represent one of the following formulae (131)˜(140),wherein Ra˜Rz are independently selected from the group consisting of H, CmH2m+1 (m=1˜15), OCpH2p+1 (p=1˜15), CH2[OC2H4]nOCH3 (n=1˜30), and [OC2H4]qOCH3 (q=1˜30).
