Outline of Research at the Start

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.
