A Full Physical Strategy for Electrical Contacts on Laser‐Induced Graphene (LIG) Electrodes

Advanced Electronic Materials, EarlyView.
A fully dry fabrication strategy combining PVD and dual‐laser processing enables direct integration of laser‐induced graphene with metallic current collectors. Ultralow Au‐LIG contact resistance is achieved without binders, adhesives, or chemical treatments, while preserving electrochemical performance.

Experimental Evidence for the Impact of Copper Microstructure on Residual Stress of Through Silicon Via

Advanced Electronic Materials, EarlyView.
The impact of Cu microstructure on the thermomechanical residual stress of TSVs with a diameter of 3 μm$\umu{\rm m}$ is investigated by comparing Raman stress imaging and EBSD grain characterization. By correlating Raman‐imaged TSV stress with Cu grain structure, direct experimental evidence is provided to highlight the direct correlation between ...

Multiscale Perspectives on Perovskite Instability: From Atomistic Deformation to Device Degradation in Perovskite Solar Cells

Advanced Energy Materials, EarlyView.
Multiscale perspectives on how excess charges in soft lead halide perovskites induce operational instability in photovoltaic devices are presented. Localized carriers formed under thermodynamic non‐equilibrium states modify atomistic interactions and drive lattice distortions, accelerating device degradation.

From Laboratory to Industry: Evaporating Functional Layers at High Rates for Fully Textured Perovskite/Silicon Tandems

Advanced Energy Materials, EarlyView.
Perovskite/silicon tandem solar cells exhibit outstanding efficiencies; however, the development of scalable and high‐throughput manufacturing processes remains a critical challenge. Here, we demonstrate accelerated deposition of multiple functional layers via high‐rate thermal evaporation without compromising film quality or device performance.
