Impact of Transition Metals and Electrocatalyst Layer Thickness on the Pt‐Based Cathodes of Proton Exchange Membrane Fuel Cells – Do Multimetallic Electrocatalysts Necessarily Yield an Improved Performance?

Advanced Energy Materials, EarlyView.
Nonnoble transition‐metals (TMs) in PtCuNi/C catalysts have a dual influence in proton‐exchange membrane fuel cell cathode catalyst layer. While TMs act as a “sacrificial component” of PtCuNi/C, inhibiting Pt dissolution from the PtMx nanoparticles bearing the active sites, they promote the formation of separate catalysts and ionomer domains in the ...

Effect of Propagating Dopant Reactivity on Lattice Oxygen Loss in LLZO Solid Electrolyte Contacted with Lithium Metal

Advanced Energy Materials, EarlyView.
The decomposition of Nb‐substituted LLZO solid electrolytes is reported through a propagating reaction between Nb5+ dopants and the Li metal electrode. This work suggests dopants that segregate to interfaces/grain boundaries in LLZO will exhibit reactivity that can propagate into bulk and shed light on new mechanisms for the problematic role of oxygen ...

Interface Topology and Wetting Dynamics of Laser‐Induced Bonds Between Aluminum Foil and Silicon Nitride Passivation in Solar Cells

Advanced Energy Materials, EarlyView.
Metallization in photovoltaics faces challenges due to silver dependency. This study explores Laser Metal Bonding (LMB), an ultra‐rapid, ablation‐free process enabling robust aluminum‐to‐silicon nitride connections while preserving passivation layers and cell efficiency. Combining experiments and simulations, key adhesion mechanisms, thermal thresholds,

The Value of Device Characterization for the Optimization of Organic Solar Cells

Advanced Energy Materials, EarlyView.
Using the example of organic photovoltaics (OPV), this study examines whether and when additional measurements can be helpful in process optimization. A virtual laboratory based on real solar cells serves as a benchmark function to compare two different approaches for process optimization, namely black‐box optimization (black circle) and model‐based ...

Dynamic Cycling of Ultrathin Li Metal Anode via Electrode–Electrolyte Interphase Comprising Lithiophilic Ag and Abundant LiF under Carbonate‐Based Electrolyte

Advanced Energy Materials, EarlyView.
The silver trifluoromethanesulfonate (AgTFMS) simultaneously forms metallic Ag and abundant LiF on the Li metal surface after dissolution in carbonate‐based electrolyte, whereas lithium trifluoromethanesulfonate (LiTFMS) only generates LiF‐rich solid‐electrolyte interphase (SEI).
