Abstract

A novel zinc porphyrin (5,10,15-tri-dodecoxyphenyl-20-(4-hydroxyphenyl-azo-benzenyl)-porphyrinatozinc (tdhab-ZnP)) with benzenyl-azo-phenolic group, able to adsorb on the nanocrystalline-TiO₂ film, has been synthesized. We constructed a dye-sensitized solar cell based on the nanocrystalline-TiO₂ hierarchical structure film, with a power conversion efficiency of 4.15 % and a high current density of 14 mA/cm² under AM 1.5 irradiation. UV-Vis absorption spectra measurements indicated that the tdhab-ZnP molecules formed a charge transfer complex with TiO₂ nanoparticles (NPs) through the phenolic group. Cyclic voltammetry measurement showed that the charge separation resulting from the tdhab-ZnP excited singlet state to the conduction band (CB) of TiO₂ and charge shifting from the I^-/I^-₃ couple to the porphyrin radical cation were thermodynamically feasible.
