Molecular Locking with All‐Organic Surface Modifiers Enables Stable and Efficient Slot‐Die‐Coated Methyl‐Ammonium‐Free Perovskite Solar Modules

The power conversion efficiency (PCE) of the state‐of‐the‐art large‐area slot‐die‐coated perovskite solar cells (PSCs) is now over 19%, but issues with their stability persist owing to significant intrinsic point defects and a mass of surface imperfections introduced during the fabrication process....
