Here, multifunctional small molecule potassium trifluoromethanesulfonate (TFSK) is employed as an interlayer to efficiently bridge SnO₂ and the buried perovskite film, simultaneously regulating interfacial energetics and morphology. This strategy provides several advantages: (1) TFSK passivates oxygen vacancy defects and surface hydroxyl groups on SnO₂, while also improving energy level alignment; (2) TFSK modification induces a loose and porous morphology in PbI₂, facilitating the diffusion of ammonium salts and promoting sufficient ionic reactions to high-quality FAPbI₃ films; (3) TFSK interacts strongly with perovskite through Lewis acid–base interaction (between S=O groups and uncoordinated Pb²⁺) and hydrogen bonding (between F⁻ and formamidinium cations), significantly suppressing non-radiative recombination. Consequently, the quality of both SnO₂ and perovskite films is significantly improved, which greatly boosts the power conversion efficiency of small-size PSCs to 25.82%, with a high open-circuit voltage of 1.19 V, a minimal voltage loss of 0.341 V, and negligible hysteresis.

Despite the considerable promise of interfacial storage mechanisms in advancing next-generation batteries, the field lacks a coherent theoretical framework and universal design principles to fully harness their potential across diverse material systems and device architectures. This review provides a fundamental understanding of interfacial storage mechanisms while elucidating their impacts on electrochemical performance.

However, the problems of weak luminescence intensity and poor thermal stability have generally been exhibited by the near-infrared fluorescent materials reported to date. This article synthesized a series of Ca₃ZrNbGa₃O₁₂: Cr³⁺ phosphors by the high-temperature solid-phase method. Under 342 nm excitation, the phosphors produced emission light covering the wavelength range of 650–1150 nm. The luminescence center was 783 nm, corresponding to the ⁴T₂ → ⁴A₂ transition of Cr³⁺, and the full width at half maximum (FWHM) was 129 nm. Subsequently, with the continuous introduction of Yb³⁺ into the system, the ²F_5/2 → ²F_7/2 transition of Yb³⁺ generates multiple luminescent centers in the near-infrared region, thereby broadening the spectral coverage range. The incorporation of Yb³⁺ ions enables efficient energy transfer from Cr³⁺ to Yb³⁺ in the system. When the concentration of Yb³⁺ is 8%, the energy transfer efficiency reaches 64.1%. The Photoluminescence quantum yield (PLQY) was also improved from 41.4% of Ca₃ZrNbGa₃O₁₂: 0.7% Cr³⁺ to 69.3% of Ca₃ZrNbGa₃O₁₂: 0.7% Cr³⁺, 0.6% Yb³⁺.

In this study, SA modified electrodes were developed by anchoring transition metal atoms (Fe, Co, or Cu) onto nitrogen-doped graphene (N–C) via M–N–C coordination, synthesized through a ball milling–pyrolysis method. Electrochemical impedance spectroscopy measurements demonstrated a significant reduction in electrochemical impedance for Fe, Co, and Cu SA electrodes, indicating an enhanced electron transfer rate at the sensor interface. To evaluate the electrochemical sensing performance of SA-modified electrodes, dopamine (DA) and hydrogen peroxide (H₂O₂)—two biologically important molecules—were selected as representative analytes. Chronoamperometry revealed that Fe SA exhibited an enhanced sensitivity toward DA, reaching 0.02 A/µM, attributed to the unique electronic structure and catalytic properties of Fe sites, whereas Co SA and Cu SA did not show a notable improvement in DA detection sensitivity compared to the N–C electrode (0.01 A/µM). In contrast, Fe, Co, and Cu SA electrodes demonstrated improved sensitivity for H₂O₂ detection, achieving 0.35, 0.28, and 0.35 A/mM, respectively, surpassing the performance of the N–C electrode (0.076 A/mM).
