Outline of Final Research Achievements |
The muon-spin relaxation (muSR) technique has been applied to organic solar-cell materials. The flush-lamp muSR technique by using a pulsed muon beam has been used for this research creating light-exited electrons in organic materials. Some possible organic solar-cell materials like Polythiophene, PC71BM, PTB7 and so on have been chosen. We have succeeded to observe the muon-spin depolarization behavior which is caused by light-exited electron when the flush lamp is turned on. This result opens a new research direction to use muSR as a microscopic method for the investigation of light-exited electrons in organic solar-cell materials from the microscopic viewpoint. In addition to this, the importance of the information of muon sites in materials has been found. This is a new valuable finding of the current research. Accordingly, we have newly started to develop a way to estimate muon sites in organic and related system by using the density functional theory.
