Abstract Introducing excess PbI 2 has proven to be an effective in situ passivation strategy for enhancing efficiency of perovskite solar cells (PSCs). Nevertheless, the photoinstability and hysteresis are still tough issues owing photolysis nature . Moreover, humidity‐related degradation films is also a difficult territory cover such strategy. Herein, synergistic reported via initiatively inducing vertical graded distribution (GPD) whole film capping cis ‐Ru(H dcbpy)(dnbpy)(NCS) (Z907) internal encapsulation (IE) layer on surface ameliorate above issues. The GPD design can enhance luminescence, prolong carrier lifetimes, ascertaining improvement elimination PSCs. Besides, introduced IE not only promote moisture thermal resistance, but inhibit Pb leakage ion migration Through synergetic regulations, resultant PSCs exhibit impressive open circuit voltage ( V OC ) 1.253 V, fill factor 81.25%, power conversion (PCE) 24.28%. maintain 91% its initial PCE at relative humidity 85% after 500 h aging 94% under continuous heating 85 °C 750 aging.

Cesium lead triiodide (CsPbI3 ) is a promising light-absorbing material for constructing perovskite solar cells (PSCs) owing to its favorable bandgap and thermal tolerance. However, the high density of defects in CsPbI3 film not only act as recombination centers, but also facilitate ion migration, leading lower PCE inferior stability compared with state-of-the-art organic-inorganic hybrid PSC counterpart. Theoretical analyses suggest that effective suppression helpful improving device performance. Herein, stable efficient γ -CsPbI3 PSCs are demonstrated by developing an acyloin ligand (1,2-di(thiophen-2-yl)ethane-1,2-dione (DED)) phase stabilizer defect passivator. The experiment calculation results confirm carbonyl thienyl DED can synergistically interact forming chelate effectively passivate Pb-related further suppress migration. Consequently, DED-treated yield champion 21.15%, which one highest among all reported date. In addition, unencapsulated DED-CsPbI3 retain 94.9% itsinitial when stored under ambient conditions 1000 h 92.8% initial constant illumination 250 h.
