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.

Abstract Bilayer 3D/2D heterojunction perovskite solar cells (PSCs) have attracted increasing interest due to great advantages of high power conversion efficiency (PCE) and ultrastability. Previous studies are mostly focused on addressing the issue poor charge transport originated from spacer cations or random phase distribution 2D in heterojunction. However, carrier recombination at surface layer is often ignored. Herein, a novel strategy passivating with thin termination (STL) proposed. It demonstrates that defects terminated by molecule 2‐amino‐5‐mercapto‐1,3,4‐thiadiazole through multi‐site interaction, leading significant suppression non‐radiative considerable improvement hole well‐aligned energy band simultaneously. As result, PSCs constructed 3D/2D/STL structure processed air achieved champion PCE 25.09% open‐circuit voltage 1.211 V (the deficient 0.349 V). The unencapsulated devices retain exceeding 90% initial after storing for 1008 h under illumination N 2 504 h. This work opens up an important, but unnoticed topic defect passivation PSCs.

Abstract A degenerated four‐wave‐mixing (FWM) process in single‐crystal (CH 3 NH )PbBr (MAPbBr ) is reported, where 150‐fs laser pulses at 1.33 µm are employed as the pump. Two pump photons interact with a single crystal, producing another two higher and lower energies, respectively. One of FWM‐generation sidebands tuned from ∼1.23 to 1.21 other ∼1.43 1.48 for center wavelength, fluence increased 2.6 11.69 mJ cm −2 . The self‐phase modulation induced by strong through optical Kerr effect responsible tuning dynamics. Transient spectroscopy not only verifies FWM scheme interacting waves but also reveals interference dynamics between FWM‐generated probe pulse. In particular, angular dependence generation supplies direct evidence phase‐matching geometry. Using experimental data, nonlinear refractive index coefficient 1.19 × 10 −14 2 W −1 MAPbBr determined.
