Planar Organic Molecule with Acceptor-Donor-Acceptor structure based on Benzodithiophene in Application as Solar Cells Donor Unit |
| 초록 |
A planar acceptor-donor-acceptor (A-D-A) structured organic molecule, (BDT-HTOX), was designed and synthesized for the application as donor material in inverted type organic solar cells (OSCs). Benzodithiophene (BDT) was used as central donor (D) unit and phenylisoxazol (OX) as acceptor (A) unit, while hexylthiophene (HT) ring as a -bridge to extend the effective conjugation length and increase the solubility of the material. For devices, PC71BM is employing as the electron acceptor unit. Herein, the optoelectronic properties of BDT-HTOX as well as the devices performances had been investigated. UV-Vis absorption and electrochemical measurements revealed the HUMO/LUMO level at -3.72 eV/ -5.44 eV with an optical band gap of 1.72 eV for BDT-HTOX. While the devices based on BDT-HTOX : PC71BM = 1:1 in chlorobenzene as a solvent for solution processed organic solar cells showed the best performance. |
