Enhancement of light-energy conversion efficiency by multi-porphyrin arrays of porphyrin-peptide oligomers with fullerene clusters
Article Abstract:
The study reports novel photovoltaic cells composed of phorphyrin-peptide oligomers and fullerene clusters, which are deposited on nanostructured SnO2 electrodes. It concluded that the formation of a molecular assembly between fullerene and multi-porphyrin arrays with a polypeptide backbone controls the electron transfer efficiency in the supramolecular complex, which is essential for the light-energy conversion.

Organized assemblies of single wall carbon nanotubes and porphyrin for photochemical solar cells: Charge injection from excited porphyrin into single-walled carbon nanotubes
Article Abstract:
The photochemical properties of ordered assemblies of protonated porphyrin and single-walled carbon nanotube (SWCNT) and their utilization in a photoelectrochemical cell for light-harvesting application are investigated. The photoelectrochemical effect of SWCNT and porphyrin assembly has indicated the usefulness of carbon nanotubes in promoting charge transfer and charge transport in photochemical solar cells.
