Abstract
In this work, a new zinc meso-tetra[3-(1H-imidazol-1-yl)phenyl]porphyrin (ZnP) was synthesized. Further, the porphyrin ZnP was immobilized by metal-ligand axial coordination (ZnP-A) and a metal-ligand edged binding approach (ZnP-Zn-A) on the nanostructured TiO2 electrode surface modified with coordinating ligand functionality, isonicotinic acid (A). The performances of the assemblies-sensitized solar cells were performed under irradiance of 100 mW cm−2 AM 1.5G sunlight. Photo-electrochemical studies reveal significantly improved performance of the assembly ZnP-A. These assemblies can afford a fertile base for further design and fabrication of new supramolecular solar cells in future.
