Abstract Due to its soft lattice characteristics, all‐inorganic cesium lead halide (CsPbI 3‐x Br x ) perovskite is vulnerable external environmental stress such as moisture, polar solvent, illumination. resulting in structural defects (V I , i etc.) and ion mobility. However, most of the prior arts focus on short‐term static passivation, which has a negligible effect formed during solar cell operation. Herein, photoisomerizable molecule, 1,3,3‐trimethylindolino‐8′‐methoxybenzopyrylospiran (OMe‐SP), exhibiting light‐driven pre‐isomeric (SP) post‐isomeric (PMC) configurations, employed an interfacial protective layer top CsPbI . The present strategy not only effectively suppresses migration halogen ions, but also enables sustainable passivation defects, thereby significantly reducing charge recombination retarding degradation. Consequently, OMe‐SP‐modified cells (PSCs) exhibit superior stability, maintaining 91% their initial efficiency after aging 1032 h under maximum power point (MPP) tracking continuous one sun Meanwhile, achieves impressive conversion 22.20%, stands highest among cells. Overall, implementation this robust provides defect suppression for achieving both high PCE stable inorganic perovskite.

Abstract Self‐assembled monolayers (SAMs) have significantly improved the device performance of inverted perovskite solar cells (PSCs). However, inadequate chemical bonding affinity between SAMs and substrate as well uneven SAM distribution can lead to decrease in performance. Herein, study reports a bilayer NiO x hole transport layer (HTL), consisting ultrathin buffer film prepared through atomic deposition (ALD‐NiO ) spin‐coated (Spin‐NiO ). The work function difference two films will facilitate transfer from ALD‐NiO Spin‐NiO /Spin‐NiO structure. These holes undergo surface hydroxylation reactions with water molecules on surface, generating additional hydroxyl groups covalently bonded film, which provide more anchoring sites for molecules. Stable covalent bonds be formed subsequently coated film. As result, better coverage molecular arrangement obtained. /SAM composite HTL also demonstrates superior charge capability thermal stability. For small area PSCs (0.06 cm 2 by using HTL, champion power conversion efficiency (PCE) 25.25% is achieved, stabilities are improved.

Abstract A stable and compact fullerene electron transport layer (ETL) is crucial for high‐performance inverted perovskite solar cells (PSCs). However, traditional fullerene‐based ETLs like C 60 PCBM are prone to aggregate under operational conditions, a challenge recently recognized by academic industrial researchers. Here, we designed synthesized novel cross‐linkable molecule, bis((3‐methyloxetan‐3‐yl)methyl) malonate‐C monoadduct (BCM), use as an ETL in PSCs. Upon low‐temperature annealing at 100 °C, BCM undergoes situ cross‐linking form robust cross‐linked (CBCM) film, which demonstrates excellent mobility suitable band structure efficient Our results show that PSCs incorporating CBCM‐based achieve impressive efficiency of 25.89 % (certified: 25.36 %), significantly surpassing the 23.25 PCBM‐based devices. The intramolecular covalent interactions within CBCM films effectively prevent aggregation enhance film compactness, creating internal encapsulation mitigates decomposition ion migration components. Consequently, exceptional stability, maintaining 97.8 their initial after 1000 hours maximum power point tracking, compared only 78.6 retention devices less than 820 hours.

However, there are only scattered reports available unreacted distribution, solvent effect, cost‐performance for surface engineering, calling low‐cost strategies address these challenges. Here, distribution species visualized effect solvent‐dominated reconstruction performance pointed. Experimental computational studies reveal that lattice distortion caused interaction between solvents crystals increases non‐radiative losses, thus deteriorating device performance.
