| Outline of Final Research Achievements |
This study aims for developing highly-efficient OPV organic materials based on biradicaloid molecules, by exploiting singlet fission (SF) phenomenon that produces two triplet excitons from one photon. In this study, we succeeded in the development of efficient synthesis of a biradicaloid, Bisanthene. Furthermore, the transient absorption measurement of a bisanthene film formed on a substrate revealed that the triplet species are generated by the SF mechanism. In the evaluation of the solar cell, a p-n junction was prepared by Bisanthene and fullerene and its solar cell performance was investigated. Solar cell characteristics: short-circuit current 1 mA / cm2, the open-circuit voltage 0.34 V, FF 0.48, and conversion efficiency 0.16%: showed a good performance.
