Research Highlights: Uncovering the Crystalline Packing Advantages of Asymmetric Y-series Acceptors for Efficient Additive-insensitive and Intrinsically Stable Organic Solar Cells
Organic solar cells (OSCs) hold immense potential as renewable energy sources, but the performance-stability conundrum remains a major obstacle on the road to OSC commercialization. To address this, in this study, molecular packing behaviors of representative state-of-the-art Y-series non-fullerene acceptors (NFAs) are studied, focusing on their terminal group symmetries. Utilizing grazing-incidence wide-angle X-ray scattering, the distinct crystalline packing structure of these NFAs is revealed.… Read More
