Material Informatics (MI) have attracted much attention in recent years. Based on the concept of MI, we have made an attempt to statistically analyze the correlation between chemical structures and device performances of polymer-fullerene solar cells and to propose a high-efficient material. Experimental data obtained using time-resolved microwave conductivity (TRMC) are also involved to compensate the gap between the statistics and real devices. We discuss the correlation between efficiency and the structure on the basis of structural empirical parameters and TRMC evaluations.
