Microwave Annealing for Fast and Effective Hydrogen Activation in Polycrystalline Silicon Passivating Contacts

Advanced Energy and Sustainability Research, EarlyView.
Hydrogenation is a crucial step in the fabrication of high‐efficiency silicon solar cells, which is currently integrated into the fire‐through screen‐printing metallization. Truong et al. report on the use of microwave annealing as an effective decoupled method to activate hydrogen for poly‐Si passivating contacts.

Tungsten Carbide Nanoparticles Embedded in Carbon Nanofoam Composites for Efficient Electrocatalytic Hydrogen Evolution

Advanced Energy and Sustainability Research, EarlyView.
A tungsten carbide nanoparticles/carbon nanofoam composite is presented as an efficient electrocatalysts towards hydrogen evolution reaction. The simultaneous ablation of tungsten and carbide via pulsed laser deposition results in homogeneous and dense dispersion of tungsten carbide particles in the carbon matrix.

Machine‐Learning‐Based, Feature‐Rich Prediction of Alumina Microstructure from Hardness

Advanced Intelligent Discovery, EarlyView.
Herein, high‐performance generative adversarial network (GAN), named ‘Microstructure‐GAN’, is demonstrated. After training, the high‐fidelity, feature‐rich micrographs can be predicted for an arbitrary target hardness. Microstructure details such as small pores and grain boundaries can be observed at the nanometer scale in the predicted 1000 ...
