A low band gap donor-acceptor conjugating new copolymers based on 2-pyran-4-ylidemalononitrile derivatives for organic solar cells |
| 초록 |
Mixtures of conjugated polymers and fullerene derivative (PCBM) command considerable attention for application in organic solar cells. In order to improve their efficiency, the design of new materials that absorb at longer wavelengths (or low band gab) is of substantial interest. We synthesis and characterize new copolymers based on 2-pyran-4-ylidenemalononitrile and derivatives of dialkoxy-divinylbenzene and fluorene to get low band gap and high Voc. A series of copolymers with and 2-pyran-4-ylidene-malononitrile (PM) derivatives were synthesized successfully through the Heck coupling reaction and Suzuki coupling reaction. In this presentation, the optical, electrochemical, and photovoltaic properties of the blend of new copolymers and PCBM will be discussed. |
