Outline of Final Research Achievements

In this investigation, we aim to develop high photosensing systems, which converts one photon to electricity, based on the organic-inorganic hybrid interface. We succeeded to make new hybrid device structures with a highly sensitive photoelectric conversion property: 1) A high voltage output (>1.2 V) can be induced by organic-inorganic hybrid photovoltaic cell sensitized with metal-ligand interfacial complexes. 2) A high sensitive photoelectric conversion was achieved by photomultiplication properties of the interfacial lanthanide complex on a mesoporous TiO2 film.
