Pyridine Integrated Hole Transport Material for Hysteresis-less Long-term Stable and Efficient Perovskite Solar Cells |
| 초록 |
Since hole transport material (HTM) plays a significant role in enhancing the power conversion efficiency (PCE) and stability of perovskite solar cells (PSCs). Here, we rationally designed and synthesized a new class of HTM. We have systematically investigated its photophysical, thermal, electrochemical and charge transport properties of HTM which reveals that the HTM is potential candidate for making PSCs. The key significant findings are observed in this work. The HTM based PSC accomplished an average PCE of 16.46% with outstanding long-time durability over 30 days with minimal reduction of its initial PCE and negligible hysteresis. In addition, new HTM based PSC cell enhanced the film uniformity and smooth morphology with improved hydrophobicity thereby long-term stability. Overall, we believe that this approach would be an effective design strategy among the existing library and pave for high performance PSCs with less hysteresis and long-term stability. |
