Synthesis and Photovoltaic properties of Low band gapPolymers based on 2-pyran-4-ylidemalononitrile derivatives, 10-hexylphenothiazine and 9,9-dihexylfluorene. |
| 초록 |
Organic photovoltaic systems exhibiting low cost and high efficiency in solar energy conversion are strategically important and actively pursued worldwide. In order to improve their efficiency, the design of new materials that absorb at longer wavelengths (or good electron mobility) is of substantial interest. We synthesize a series of new copolymers based on 2-pyran-4-ylidenemalononitrile derivatives and 10-hexyl-phenothiazine or 9,9-dihexylfluorene to get low band gap and high Voc. A series of copolymers were synthesized successfully through the Suzuki coupling reaction. In this report, the optical, electrochemical, and photovoltaic properties of the blend of new copolymers and PCBM will be discussed. |
