| 제목 | Halogenation of Polymer Backbone for Efficient Polymer Solar Cells |
| 초록 | Bulk heterojunction polymer solar cells (PSCs) have attracted much attention because of their mechanical flexibility, light weight and low cost. Recently, PSCs consisting of fluorine have been reported to exhibit accelerating electron transfer lead to high power conversion efficiencies (PCEs) due to their high electron negativity. In addition, it has an advantages to provide more planar backbones and exhibit lowering the highest occupied molecular orbital (HOMO) levels. However, fluorinated polymers have some problems such as severe aggregation and low yields of fluorine exchange. So, we need chlorination to overcome disadvantages instead of fluorination. In the study, we synthesized and designed a chlorinated donor-acceptor (D-A) polymer. Chlorinated polymer showed high yield in overall synthesis steps and affordable crystallinity with blended non-fullerene acceptors. These results demonstrate that chlorination is promising method to reach the high PCEs of PSCs. |
