Control of Nanoscale Morphology in Polymer Solar Cells using Conjugated Polymers Incorporating Fullerene Compatible Functional Groups |
| 초록 |
Nanomorphology control in bulk heterojunction (BHJ) organic photovoltaics cell is one of the most important issues to achieve a PCs). Poor miscibility of conjugated polymers with fullerene derivatives often induces large phase separation in the polymer:fullerene BHJ film, resulting in low photocurrent generation. In the presentation, we introduce a facile and generally applicable method to improve the polymer’s compatibility with fullerene derivatives. We developed a series of conjugated polymers (PTBDCBXs) incorporating a functional group which can effectively interact with fullerene derivatives. Interestingly, the morphology of the BHJ film was remarkably improved with 10 nm scale phase separation. As a result, the solar cell device employing PTBDCBX showed a PCE more than 8% due to improved photocurrent densities. Regarding the relation of the polymer’s chemical structure to morphological properties and the solar cell performance, detailed mechanism studies will be presented. |
