Modification of the Chemical Structures Based on Same Conjugated Backbones by Changing Charge Transports for Efficient Polymer Solar Cells |
| 초록 |
The design of conjugated molecules is so important to enhance their physical, optical and electrochemical properties for high performance organic electronics. Through the development of conjugated polymers as donor unit based on fullerene derivatives, the innovative growth kept going on from now in polymer solar cells. In this study, we designed the conjugated donor polymers with well-matching optical absorption range and energy levels alignment by controling charge transport flows in the same backbones. In order to know definitely phenomena, we choose and modified the high performance D-A backbone of P(DTffBT-BiT)-2OD with fullerene derivatives. As the results, we reached high performance using two polymers of DTffBT acceptor unit and modified TbT donor units with fullerene and non-fullerene derivatives, respectively. |
