| 研究開始時の研究の概要 |
Different designed molecules were screened through theoretical calculations to preliminary estimation of HOMO and LUMO energy level of the newly designed molecules. Fluorinated Napthothiadiazole (FNTz) will be used as the central unit and various terminal units will be examined to achieve the desired semiconductors with necessary band gaps compatible with P3HT as donor. The synthesis of molecules will be started soon and after that different physical properties will be estimated. Newly synthesized molecules will be employed to use in the Organic solar cell device to check their efficiency.

| 研究実績の概要 |
The overall concept of this research is to develop novel π-conjugated molecules as an electron acceptor material compatible with P3HT-based donor for the large area air-stable organic solar cell. Till now, fluorinated naphthothiadiazole-based electron deficient new molecules with noncovalent conformational locks between S…N or N…F of the linker part has been already successfully synthesized. Different linker with are used for precisely adjust the molecular LUMO level, electron transfer ability in the mixed thin film, and miscibility with P3HT-based donor. Physical properties measurement such as absorption spectroscopy, cyclic voltammetry measurements are going on to check their compatibility with P3HT to be utilized as an nonfullerene acceptor for the OPV devices in ambient condition.
