These defects, most likely undercoordinated Pb and halide ions, must either be removed or passivated if cell efficiencies are to approach their theoretical limit. In this work, a universal double‐side polymer passivation approach is introduced using ultrathin poly(methyl methacrylate) (PMMA) films. Very high‐efficiency (≈20.8%) perovskite cells with some of the highest open circuit voltages (1.22 V) reported for the same 1.6 eV bandgap are demonstrated. Photoluminescence imaging and transient spectroscopic measurements confirm a significant reduction in nonradiative recombination in the passivated cells, consistent with the voltage increase. Analysis of the molecular interactions between perovskite and PMMA reveals that the carbonyl (CO) groups on the PMMA are responsible for the excellent passivation via Lewis‐base electronic passivation of Pb<jats:sup>2+</jats:sup> ions. This work provides new insights and a compelling explanation of how PMMA passivation works, and suggests future directions for developing improved passivation layers.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1383670320550232199","@type":"Researcher","foaf:name":[{"@value":"Jun Peng"}],"jpcoar:affiliationName":[{"@value":"Research School of Engineering The Australian National University  Canberra ACT 2601 Australia"}]},{"@id":"https://cir.nii.ac.jp/crid/1383670320550232205","@type":"Researcher","foaf:name":[{"@value":"Jafar I.
