Abstract Recently, the inverted CsPbI 3 perovskite solar cells (PSCs) have attracted extensive attentions due to their potential combine with silicon for tandem devices theoretical power conversion efficiency (PCE) of 44%. However, reported self‐assembled molecules (SAMs) as hole selected layer PSCs poor wettability and serious agglomeration, which greatly limits stability PSCs. To address above problem, niobium pentachloride (NCL) is applied prevent SAMs agglomeration a homogenous film hydrophilic surface. The optimized surface facilitates deposition cesium lead triiodide (CsPbI )film an enhanced referred orientation, suppressed defects, released stress. Consequently, NCL‐treated achieved champion PCE 21.24%, highest value all‐inorganic device maintained 97.61% initial after 1000 h storage in air, 92.27% tracking at maximum point (MPP).

Abstract Self‐assembled monolayers (SAMs), particularly those molecules composed of carbazole and phosphonic acid, are widely employed as effective hole‐selective layer (HSL) in inverted perovskite solar cells (PSCs). However, the insufficient chemical bond formation with metal oxides (ITO) self‐aggregation solvents acid SAM led to non‐uniform HSL, which turn affect power conversion efficiency (PCE) stability PSCs. Herein, a series benzoic materials (BAs), including p‐fluorobenzoic (FBA) p‐methylbenzoic (MBA), used post‐assembly effectively fill voids between [4‐(3,6‐dimethyl‐9H‐carbazole‐9‐yl)butyl]phosphonic (Me‐4PACz) form denser facilitates passivation buried interface. In addition, post‐assembled BAs different dipole moments can adjust work function Me‐4PACz facilitating transport extraction charge carriers. Consequently, PSCs based on Me‐4PACz/FBA HSL realize champion PCE 25.58%. Moreover, unencapsulated devices maintain 82% 94% after 800 h outdoor storage (RH≈60%) 2000 glove box, respectively. This technique enhances both device, blazing simple pathway for further development
