The Improvement of Interconnectivity in Benzo[1,2-b:4,5-b′]-Dithiophene-Based Random Copolymers via Incorporating Pyrene Unit by Enhancing π-π Stacking |
| 초록 |
We have synthesized and characterized a series of benzo[1,2-b:4,5-b′]-dithiophene-based random copolymers depending on the concentration of pyrene units. Concentration-dependent pyrene-driven self-assembly in the copolymers was systematically investigated using by various measurements such as UV-Vis spectrum, cyclic voltammetry, AFM and TEM analysis. We found that appropriate quantity of the Py moieties enabled the Py−Py interactions to propagate over many polymer chains to form a highly interconnected structure that improved the hole transport pathways and, thus, the photovoltaic performances of resulting bulk heterojunction polymer solar cells (5.03 → 7.52%). |
