Outline of Final Research Achievements |
Our comprehensive researches revealed that the linker structures in the porphyrin-nanocarbon covalent composites have a large impact on their optical and photophysical properties. Specifically, moderate length-spacers between donor and acceptor were found to be essential to produce a long-lived charge-separated state efficiently. Fast decay of photoinduced charge-transfer states (i.e., exciplex state) to the ground state was observed in not only simple donor-acceptor linked systems, but also more complex dye-semiconducting electrode interface for dye-sensitized solar cells and donor-acceptor mixed interface for organic thin film solar cells. Integrated views and interpretation on the undesirable unique phenomena have been developed to give us a universal guideline on efficient photoinduced charge separation.
