Abstract
Energy collection in photosynthetic microorganisms occurs through vectorial energy transfer along organized assemblies of chromophores. This process has inspired many research groups and yielded numerous examples of self-assembled photoactive structures. Dye sensitization of solar cells usually requires covalent anchoring of dyes onto the surface of metal oxides. A new porphyrin derivative that self-assembles upon non-covalent interaction with a surface has been designed and characterized by AFM. Interaction with metal oxide surfaces is further documented by the sensitization of metal oxide surfaces and the generation of photocurrent in non-optimized dye sensitized solar cells.
