Asymmetric Fluorinated Spiro Hole‐Transport Materials Enabled by a Rapid Core‐Forming Strategy for Blade‐Coated Perovskite Solar Cells
ABSTRACT Developing hole‐transporting materials (HTMs) that simultaneously enable high efficiency, stability, and scalable processing remains a key challenge for perovskite solar cells (PSCs). Here, we report the facile synthesis of asymmetric fluorinated spiro‐type HTMs that integrate molecular design with scalable fa...
