Outline of Final Research Achievements

In this project, we developed efficient photoelectronic conversion system by bridging basic science and application of organic electronics. We have synthesized a variety of new organic semiconductior materials by newly developed synthetic reactions, which leads to enhanced conversion efficiency of organic photovoltaic devices. In addition, we succeeded in observation of nucleation process of organic molecules for the first time by high-resolution electron microscopy. The new understanding on molecular-level phase-separation mechanism also resulted in improvement of device performances.
