Semi-Crystalline A1-D-A2 Benzotriazole based Polymer: Synthesis and Characterization for High Efficient Polymer Solar Cell |
| 초록 |
The development of new semiconducting polymers for highly efficient polymer solar cells (PSCs) has been still challenging. This study reports that by incorporating benzotriazole as a second electron-deficient monomer in benzothiadiazole conjugated polymers enables narrowing the optical band gap to ≈1.66 eV. With a planar polymeric backbone formed via traditional hydrogen bonding H---F, H---O, H---N and noncovalent interactions such as O---S, N---S and S---F interactions, leading to highly crystalline morphology in the film. Bulk heterojunction PSCs were fabricated based on the blend of the polymers and PCBM with a weight ratio of 1:1. The device performance is dramatically improved as the additive DIO was added, due to enhanced film morphology. Power conversion efficiency (PCE) up to 7.00% with JSC of 14.64 mA cm-2, VOC of 0.75V, and FF of 0.64 has been achieved. |
