Demixing and Crystallization Kinetics Control the Stability of Organic Solar Cells

With the emergence of non-fullerene electron acceptors, the performance of organic solar cells has seen tremendous increase, approaching commercial viability. Further developments are still needed to achieve highly stable devices under device operational conditions. Dr. Huawei Hu and Prof. Harald Ade have recently revealed the role of demixing and crystallization kinetics on the morphology and stability of non-fullerene solar cells in a paper published Advance Materials. According to their findings, the fundamental underlying thermodynamic and kinetic aspects of non-fullerene acceptors plays an important role in determining the stability of organic solar cells.

Prof. Ade is a Goodnight Innovation Distinguished Professor and director of ORaCEL.
