Design and Synthesis of 2D A1-π-A2 Copolymers Impact on Fullerene Network for Efficient Polymer Solar Cells |
| 초록 |
A new building block of two-dimensional (2D) A1-π-A2 copolymers for P(dDTPz-ID) and P(dDTPz-DTBT) was designed and synthesized. Their structures have two strong acceptor units (isoindigo and benzothiadiazole derivatives) in the backbone, respectively. It displayed a benefit of A1-A2 building blocks, which is complementary and broad light absorption from 300 to 700 nm due to acceptors with different withdrawing strengths. Also, the introduction of dangling-thiophene unit allowed the formation of 2D-strcuture, which led to effective inter-chain packing of PC71BM for both copolymers. Two copolymers exhibited enhanced π-π stacking properties compared to polymer-PC71BM blends and had predominant face-on structure, which was confirmed by XRD. In conclusion, the inverted device fabricated with optimized condition for P(dDTPz-DTBT), thus obtained 5.0 % of best power conversion efficiency (PCE). |
