Recent Advances in Wide‐Bandgap Perovskite Solar Cells

open access: yesAdvanced Materials, EarlyView.
Ubiquitous defects predominately account for photo‐instability and open‐circuit voltage losses in wide‐bandgap perovskite solar cells (WBG PSCs). This review comprehensively presents the underlying impact mechanisms, summarizes the advanced optimization strategies across various functional layers and their interfaces to develop efficient and stable WBG

Characterization and Inverse Design of Stochastic Mechanical Metamaterials Using Neural Operators

open access: yesAdvanced Materials, EarlyView.
This study presents a DeepONet‐based machine learning framework for designing stochastic mechanical metamaterials with tailored nonlinear mechanical properties. By leveraging sparse but high‐quality experimental data from in situ micro‐mechanical tests, high predictive accuracy and enable efficient inverse design are achieved.

Charge Transport and Carrier Polarity Tuning by Electrolyte Gating in Nickel Benzenehexathiol Coordination Nanosheets

open access: yesAdvanced Materials, EarlyView.
This work reveals that charge transport in nickel benzenehexathiol coordination nanosheets is governed by variable‐range hopping reflecting structural disorder. Electrolyte gating induces a switch in dominant carrier polarity from p‐type to n‐type and leads to an improvement in thermoelectric performance.

Water Oxidation to Hydrogen Peroxide Over a Super‐Aerophilic Graphite Catalyst

open access: yesAdvanced Materials, EarlyView.
Design of super‐aerophilic graphite catalyst capable of trapping in situ produced oxygen gas on its surface under the electrolyte environment. By so doing, it is able to moderate intermediate species binding, which is critical to enabling the two‐electron water oxidation reaction to hydrogen peroxide.
