| Outline of Final Research Achievements |
In this investigation we were successful to clarify the functional mechanisms of the chlorophyll-derivatives based bio-inspired organic solar cell that mimic the natural photosynthesis. We were also successful to enhance the photovoltaic performance of this bio-inspired organic solar cell using hydroquinone redox-mediator. In addition, we were successful to construct the artificial light-harvesting system that exceeds the limit of the natural light-harvesting capacity by the incorporation of the higher plant carotenoid, which possesses the ICT character in its excited state, to the bacterial LH1 light-harvesting system. Excitation energy-transfer and relaxation dynamics of this artificial antenna were fully addressed by ultrafast laser spectroscopy. Moreover, we have developed theoretically the novel spectroscopic technique that utilizes the quantum entangled photons as a pseudo-thermal light source that mimics the sunlight.
