Enhancement of light-energy conversion efficiency by multi-porphyrin arrays of porphyrin-peptide oligomers with fullerene clusters

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.
