Advanced Functional Materials, EarlyView.Off‐centering of cations in pavonite‐structured Ag1.75InSb5.75Se11 (AISS) breaks crystal symmetry, inducing Rashba‐like band splitting and high band degeneracy, thus enhancing Seebeck coefficients. Soft bonds between off‐centered cations and Se atoms increase phonon scattering, achieving low lattice thermal conductivity (0.22 W m−1K−1 at 723 K). Doping

A Flexible Photovoltaic Fatigue Factor for Quantification of Mechanical Device Performance
Advanced Functional Materials, Volume 35, Issue 19, May 9, 2025.The flexible Photovoltaic fatigue factor (F) quantifies mechanical and photovoltaic performance as a function of the power conversion efficiency (PCE), the strain (ε${\varepsilon}$), and the number of bending cycles (NBC) in bending tests. The strain depends on the bending radius (R) and the thicknesses of the substrate (ts) and the photovoltaic device

Heat Conduction Modulation in Incommensurate Twisted Stacking of Transition‐Metal Dichalcogenide
Advanced Functional Materials, EarlyView.The interlayer thermal conductance in twisted bilayer TMDs is initially investigated experimentally by the thermoreflectance method. The overlap of lattice vibrations within individual layers and the interlayer interactions, as elucidated through both Raman spectroscopy and molecular dynamics simulations, are demonstrated to be critical factors in ...

Advanced Functional Materials, EarlyView.Novel conjugated polymers with side‐chain π‐conjugation are developed to enhance organic thermoelectric properties. Remarkably, the pendant doping in the conjugated polymers preserved strong intermolecular ordering in the film states even at high FeCl3 dopant concentrations (16 – 32 mM), achieving a promising power factor > 10 µW m−1 K−2 across a wide ...
