In article number 1901716, Hongwei Lei, Song Zhang, Zuojun Tan, and co‐workers report a novel and efficient perovskite defect passivation strategy using silica oligomer. TEOS‐processed silica oligomer is in situ introduced into perovskite films to serve as a passivation agent (PA) for perovskite solar cells (PVSCs). Silica oligomer PA can enlarge perovskite grain sizes, prolong carrier lifetime, enhance charge carrier dynamics and reduce trap state densities, resulting in highly efficient PVSCs with good humid and thermal stability.
