| Outline of Final Research Achievements |
On the basis of the originally-designed Xe-flash time-resolved microwave conductivity technique, this project aimed at the development of measurement and analysis system that allows facile evaluation and prediction of organic photovoltaic performance. To this end, the following research topics were planned, (1) improvement of the precision and expansion of applicability, (2) establishment of evaluation and prediction method of organic photovoltaic performance as well as elucidation of fundamental physical chemistry in solar cell, and (3) application to the design and synthesis of new optoelectronic organic materials. Through the efforts during the three-year project, we have established a novel efficient evaluation system based on advanced microwave spectroscopy. Furthermore, the system was proved very effective in designing conjugated polymer/fullerene, and thus we succeeded in developing new polymers with high power conversion efficiencies.
