Tailored Electro–Magnetic–Porous Multigradient Nanoarchitectonics for Absorption‐Dominated Electromagnetic Interference Shielding and Adaptive Multifunctionality

open access: yesAdvanced Science, EarlyView.
An electro–magnetic–porous multigradient nanofibrous electromagnetic interference (EMI) membrane is fabricated via shear‐induced in situ fibrillation and layer‐by‐layer assembly. Leveraging a multigradient‐induced “impedance matching–polarization–reabsorption” synergistic mechanism, the membrane achieves absorption‐dominated high‐efficiency EMI ...

Boosting the Efficiency and Mechanical Stability of Organic Solar Cells Through a Polymer Acceptor by Reducing the Elastic Modulus

open access: yesAdvanced Energy Materials, EarlyView.
Herein, PYSe2F‐T is first applied to simultaneously improve the performance and mechanical stability of organic solar cells compared with mPh4F‐TS as the counterpart. Meanwhile, a detailed crack density analysis is first employed to evaluate the relationship between mechanical stability and elastic modulus of active layers, which can be reduced by the ...

Phase Transition in Halide Double Perovskites for Solar‐To‐Chemical Energy Conversion

open access: yesAdvanced Energy Materials, EarlyView.
Disorder‐to‐order phase transition in double perovskite Cs2AgBiBr6 eliminates self‐trapped excitons and antisite defects and promotes charge separation, with over sixfold photoactivity enhancement in photocatalytic C−H bond activation. Abstract Halide double perovskites have recently garnered significant interest in solar energy conversion applications

Critical Role of Non‐Fullerene Crystalline Domains in Stabilizing Charge Separation in Bulk Heterojunction Organic Solar Cells

open access: yesAdvanced Energy Materials, EarlyView.
A crucial factor in stabilized charge generation in high‐performance PM6:Y6 organic solar cells is the LUMO level offset between mixed and pure Y6 domains. This offset enhances electron–hole spatial separation, reducing recombination losses. As the pure Y6 domain shrinks, increased bimolecular recombination significantly lowers the photocurrent and ...
