Dye-sensitized Solar Cells Using Supramolecular Porphyrin Arrays Inspired by pi-Stacking Structures of Photosynthetic Light-harvesting Complexes
A slipped cofacial pi-stacks of bis(4-carboxyphenyl)bis(1-methylimidazol-2-yl)porphyrinatomagnesium complex can be self-assembled onto TiO2 surface as a light-harvesting core. The porphyrin array allows a more favorable light-to-electricity conversion compared to the monomer analogue in dye-sensitized solar cells.
