| Outline of Final Research Achievements |
The donor(D)/acceptor(A) interface plays an important role in the exciton dissociation processes in organic thin-film solar cells. Thus, a simple method to determine the D/A mixture and interface state is desired. In this study, we proposed an analysis method of EL spectrum from charge transfer states formed at D/A interface.

| Academic Significance and Societal Importance of the Research Achievements |
本研究成果により、有機合成者により開発される新規ドナー高分子やアクセプター低分子がOPVに適、不適のスクリーニングが簡便になる上、励起子の観点からOPV特性の解析が簡便に行える。新規材料で得られるOPV特性の最大値や解釈が分かった上で、OPV薄膜の作製プロセス最適化を行えば、迅速なスピードで高効率OPVの開発が進むと考えられる。
