Supramolecular photovoltaic cells using porphyrin dendrimers and fullerenes

Organic photovoltaic cells made using supramolecular complexes of porphyrin dendrimers with fullerenes demonstrate remarkable enhancement in the photoelectrochemical performance as well as broader photoresponse in the visible and near-infrared regions relative to the reference system. This demonstrates that molecular assemblies Of C-60 and porphyrins with dendritic structures are effective in photoenergy conversion systems (see Figure).
