Suppressing Halide Segregation via Pyridine‐Derivative Isomers Enables Efficient 1.68 eV Bandgap Perovskite Solar Cells

Light‐induced phase segregation is one of the main issues restricting the efficiency and stability of wide‐bandgap perovskite solar cells (WBG PSCs). Small organic molecules with abundant functional groups can passivate various defects, and therefore suppress the ionic migration channels for phase s...
