摘要
事实证明,开发优质阳极中间膜(AIL)是提高有机太阳能电池(OSC)效率和稳定性的关键。在这项工作中,利用导电聚吡咯复合材料 PPy:PMA 来改性市售的 PEDOT:PSS。用少量 PPy:PMA 掺杂 PEDOT:PSS,PM6:L8-BO 混合薄膜的器件效率可从纯 PEDOT:PSS 的 17.7% 提高到混合 AIL 的 18.2%。性能的提高可归因于电极和活性层之间能级的更好匹配、接触电阻的降低、电荷重组的抑制以及 AIL 导电性的提高。此外,与纯 PEDOT:PSS 器件相比,基于混合 AIL 的器件具有更好的光稳定性和热稳定性。总之,我们的工作表明,协同混合阳极中间膜在提高 OSC 性能和长期稳定性方面具有巨大优势。
Polypyrrole-Decorated Hybrid Anode Interlayer for Enhancing Efficiency and Stability of Non-Fullerene Solar Cells
The development of a superior anode interlayer (AIL) has proved to be key to improving the efficiency and stability of organic solar cells (OSCs). In this work, conducting polypyrrole composite PPy:PMA was exploited to modify the commercially available PEDOT:PSS. With a small amount of PPy:PMA to dope PEDOT:PSS, the device efficiency for the PM6:L8-BO blend film can be improved from 17.7% for the pure PEDOT:PSS to 18.2% for the hybrid AIL. The enhanced performance can be attributed to better match energy levels between the electrode and the active layer, reduction on contact resistance, the inhibition of charge recombination, and increase in the electric conductivity of the AIL. In addition, compared with the devices with pure PEDOT:PSS, the devices based on the hybrid AIL exhibit better photostability and thermal stability. Collectively, our work demonstrates that a synergistic hybrid anode interlayer has great advantages in improving the performance and long-term stability of OSCs.
