Outline of Final Research Achievements

Identifying and controlling properties of grain boundaries in organic thin films is essential to reducing the energy loss of the device. In this study, we clarified the correlation between the aggregation structure (defect structure) of the molecules near the grain boundaries and their electronic properties. We demonstrated in detail what kind of grain boundary structure causes the energy loss of the devices.

Academic Significance and Societal Importance of the Research Achievements

有機薄膜太陽電池の効率改善の指針を提供しただけでなく、局所分子配向マップや粒界物性評価の手法を新たに提供した点が意義深く、今後バルクヘテロ構造などへの応用が期待される。
