Abstract
Two novel large conjugated system mesoSchiffbase substituted porphyrin dimers which contained the thienyl or pmethylphenyl functional groups have been designed and synthesized for the efficient green dyes for dyesensitized 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 redshift at the maximum absorption high fluorescence quantum yield However p101520triphenyl5porphyrinyl benzylidene aminophenyl1015202thienylporphyrin based on DSSCs reaching 286 under AM 15 G irradiation showed slightly better comprehensive properties than the p101520triphenyl5porphyrinyl benzylidene aminophenyl1015 20pmethylphenylporphyrin
