Outline of Final Research Achievements |
Recently, vast effort has been devoted to the development of photovoltaic devices by mimicking charge-separation process in natural photosynthetic systems. Improving the energy conversion efficiency of these devices is one of the most urgent social challenges. To achieve this, it is vital to understand the mechanism behind the high energy conversion efficiency of the natural photosynthetic system at the molecular level. In this study, we developed a novel methodology to quantify photoindiced electron transfer on a single molecule basis. Specifically, this method allows us to measure photoinduced electron transfer from a single electron-donating molecule to adjacent single electron-accepting molecule. The present study opens up a way for exploring the charge-separation process in the photosynthetic system at the single molecule level.
