Synthesis and characterizations of phenanthrene polymer derivatives with low band gap for organic solar cells |
| 초록 |
In recent times, there has been considerable interest about organic solar cells (OSCs) due to lightweight, inexpensive, and flexible characteristics. To produce highly efficient OSCs, active materials should have large open-circuit voltage (Voc) and short circuit current density (Jsc). Conventional thiophene derivatives have shown a high power conversion efficiency by relatively high Jsc and fill factor. However, they are limited by relatively low Voc due to high HOMO level. Generally, poly(2,7-phenanthrenylene) derivative has large band gap and deep HOMO level compared to P3HT, and it has chance to achieve higher Voc. In this presentation, we synthesized novel donor polymers containing phenanthrene backbone for improved Voc with push-pull structure to absorb wide range of the solar spectrum. We will present the material synthesis, characterization and OSC device performance using our novel low band gap donor polymers. |
