Effect of Electron Withdrawing Groups on Triphenylamine-Substituted Quinoxaline-based D-A type Conjugated Polymers |
| 초록 |
In this study, two D-A type polymeric backbone was constructed by coupling of the electron-donating chlorinated-benzodithiophene (BDT) and the electron-accepting triphenylamine-substitued quinoxaline derivatives. In addition, the strong electron-withdrawing fluorine atom and cyano unit were selectively incorporated into the quinoxaine moeity to investigate their effects on the photovoltaic properties of the polymers. After confirming the polymer properties, the photovoltaic properties of the polymers were investigated by fabricaitng the inverted-type device with the configuration of ITO/SnO/Polymers:Y6/MoO3/Ag. Interestingly, the photovoltaic properties of the polymers are strongly dependent on the type of the electron-withdrawing substituents in their structures. Therefore, this study can offer meaningful insights in the structure-property relationships of conjugated polymers for developing high performance polymer solar cells. |
