Elongating π-Conjugation using π-Bridges for Fast Hole Extraction |
| 초록 |
Charge extraction at each electrode should be efficient for high performance perovskite solar cells. We elongated π-conjugation using thienothiophene-based π-bridges in hole transport polymer for enhancing the charge transport ability of it. Polymer with π-bridge had higher crystalline ordering and hole mobility than polymer without π-bridge. Holes transferred from perovskite layer were transported to anode quickly, resulting fast hole extraction. Fast hole extraction reduced space charge inside perovskite solar cells and reduced charge carrier recombination effectively. |
