Abstract
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.
期刊介绍：
ACS Applied Polymer Materials is an interdisciplinary journal publishing original research covering all aspects of engineering, chemistry, physics, and biology relevant to applications of polymers.
The journal is devoted to reports of new and original experimental and theoretical research of an applied nature that integrates fundamental knowledge in the areas of materials, engineering, physics, bioscience, polymer science and chemistry into important polymer applications. The journal is specifically interested in work that addresses relationships among structure, processing, morphology, chemistry, properties, and function as well as work that provide insights into mechanisms critical to the performance of the polymer for applications.
