High efficiency Planar Perovskite Solar cells using polymeric hole transport material without dopant. |
| 초록 |
Recent days, organometal halide perovskite has emerged as the next-generation solar cell due to its high efficiency and superior properties. The perovskite layer is located between charge transporting layers to transport and block carriers efficiently. Especially, the hole transporting layer (HTM) is significant as it protects perovskite from the air. Thus, it is essential to develop dopant-free and hydrophobic HTM. Herein, we report a novel polymeric HTM (PTEG) using tetraethylene glycol goup. The planar perovskite solar cell employing PTEG achieves 19.8% efficiency without dopants. This efficiency is the highest record reported to date. We anticipate that this study could present a strategy for developing new polymeric HTM. |
