The addition of methylammonium chloride (MACl) significantly improves the performance and stability perovskite fabricated by two-step processes. However, its role in crystallization dynamics has not been thoroughly studied. In this work, a comparison study is carried out using different additions MACl to investigate impact dynamics. situ grazing incidence wide-angle X-ray scattering (GIWAXS) observations during annealing process revealed that amount influences crystallinity orientation perovskite. Increasing enhances wet film‘s intermediate phase strengthens out-of-plane FAPbI3 α-phase (001) planes annealing. Moreover, it was found both excessive insufficient amounts introduce defects into perovskite, which are detrimental device performance. contrast, an optimal ratio MACl-9 mg leads formation uniform large-grained films, with longest carrier lifetimes (163.7 ns) compared MACl-5 (68.4 MACl- 13 (120.1 ns). As result, mg-based solar cell achieved highest efficiency (22.63%), higher than those (21.47%) MACl-13 (20.07%).

Abstract Long-term stability and power conversion efficiency of perovskite solar cells are strongly affected by their precursor compositions intermediate phases during the fabrication process. In general, complex chemical reactions happen in a short time scale nucleation crystal growth steps. However, ex-situ characterization probes cannot capture dynamics film formation degradation. this review, we discussed ambient air-compatible in-situ that used to monitor evolution structural, morphological, optoelectronic properties films, which provides deep understanding

The inorganic perovskite CsPbI3 shows promising photophysical properties for a range of potential optoelectronic applications but is metastable at room temperature. To address this, Br can be alloyed into the X-site to create compositions such as CsPbI2Br that are stable temperature have bandgaps >1.9 eV - severely limiting solar applications. Herein, in an effort achieve phase films with <1.85 eV, we investigate alloying chlorine iodine-rich triple-halide CsPb(I0.8Br0.2-x Cl x )3 0 < 0.1. We show partial substitution iodine bromine and provides path maintain broadband terrestrial absorption while improving upon stability due chlorine's smaller size larger ionization than bromine. At moderate loading up ≈5%, X-ray diffraction reveals increasingly orthorhombic unit cell, suggesting incorporation lattice. Most notably, this accompanied by significant enhancement over Cl-free controls duration black-phase 7× elevated temperatures. Additionally, observe 5× increased steady state photoluminescence intensity (PL), along small blue-shift. In contrast, high (≈10%), accumulates second visible grain boundaries via synchrotron fluorescence microscopy negatively impacts stability. Thus, replacing fractions lattice results distinct improvement thermal quality minimally impacting bandgap.

Abstract Tin‐halide perovskite solar cells (THPSCs), while offering low toxicity and high theoretical power conversion efficiency, suffer from inferior device performance compared to lead‐based counterparts. The primary limitations arise challenges in fabricating high‐quality films mitigating the oxidation of Sn 2+ ions, which leads severe non‐radiative voltage losses. To address these issues, we incorporate rare‐earth element erbium chloride (ErCl 3 ) into PEA 0.15 FA 0.70 EA SnI 2.70 Br 0.30 effectively control nucleation crystal growth, significantly influencing morphology films. As a result, ErCl ‐processed THPSC exhibits an impressive open‐circuit ( V OC 0.83 efficiency (PCE) 14.0% with superior light air stability, = 0.77 PCE 12.8%). This ‐strategy provides feasible solution for high‐performance THPSCs by regulating nucleation/crystallization kinetics excessive defects during preparation process lead‐free perovskites. image

Abstract Metal halide perovskites (MHPs) have achieved substantial progress in their applications; however, ionic crystal character and low formation energy result poor structural stability limited morphological tunability. In particular, high relative humidity (RH) commonly causes severe MHP degradation, which poses a major obstacle to long‐term device operation. Herein, RH‐induced growth of anisotropic structures on glass surfaces is reported under 25 °C atmospheric conditions basis corrosion by moisture. Nanowires (NWs) with tunable length composition are obtained 85% RH air, water molecule‐induced facet engineering perovskite established for growth. Importantly, single‐mode photonic lasing these NWs thickness at sub‐100‐nm scale (down 75 nm ∼ 1/7 wavelength) via both one‐photon multiphoton pumping. These nanowire lasers exhibited quality factor (>3000), degree polarization (≈0.9), excellent laser irradiation. The work not only presents distinctive technique the MHPs but also endows new opportunities nonlinear optics, strong light‐matter interactions, active integrated devices.
