Abstract

Two novel large conjugated system meso-Schiff-base substituted porphyrin dimers, which contained the thienyl or p-methylphenyl functional groups, have been designed and synthesized for the efficient green dyes for dye-sensitized solar cells (DSSCs) applications. The synthesis and characterization of the large conjugated system based on porphyrin dimer derivatives have been investigated through their spectral, electrochemical, and photovoltaic performances by DSSCs study. Due to the increase of the conjugated system, the two porphyrin dimers have some large red-shift at the maximum absorption, high fluorescence quantum yield. However, p-(10,15,20-triphenyl-5-porphyrinyl) benzylidene aminophenyl-10,15,20-(2-thienyl)-porphyrin, based on DSSCs reaching 2.86 % under AM 1.5 G irradiation, showed slightly better comprehensive properties than the p-(10,15,20-triphenyl-5-porphyrinyl) benzylidene aminophenyl-10,15, 20-(p-methylphenyl)-porphyrin.
