Ag‐Induced Phase and Defect Engineering of Co‐Evaporated Sb2Se3 Thin Films for Enhanced Photovoltaic Performance

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The sequential formation of Ag2Se and AgSbSe2 phases at the Sb2Se3/Mo interface upon Ag incorporation in co‐evaporated Sb2Se3 solar cells promotes grain growth and defect passivation. These newly formed intermediate phases enhance crystallinity and suppress recombination, leading to significant improvements in open‐circuit voltage, fill factor, and ...

Similar Material Simulation Study on Dam Movement and Deformation Law of Deep Coal Seam Mining Under Dam

open access: yesEnergy Science &Engineering, EarlyView.
Aiming at the difficulties in accurately calculating the movement and deformation of small‐sized, deep‐buried dams with a significant height‐to‐depth ratio in deep fully mechanized caving mining, this study proposes to separate the analysis of surface and dam deformation.

Research on the Laws of Destructive Patterns and Control Measures of Overlying Rock in High‐Efficiency Large‐Scale Mining Faces

open access: yesEnergy Science &Engineering, EarlyView.
With the advancement of coal mining technology driving the development of working faces toward increased mining heights and extended lengths, the enlargement of face dimensions has led to expanded overlying strata failure zones and intensified ground pressure manifestations. Consequently, traditional methods for determining hydraulic support resistance

Interpretable Tree‐Based Models for Predicting Short‐Term Rockburst Risk Considering Multiple Factors

open access: yesEnergy Science &Engineering, EarlyView.
Interpretable tree‐based models integrate microseismic, geological, and mining indicators to predict short‐term rockburst risk. SHAP analysis reveals the dominant role of energy‐related features and clarifies nonlinear factor interactions, enabling transparent and reliable early‐warning in deep coal mines.

Multifactorial Screening for Fine‐Scale Selection of CCS Industrial Clusters and Hubs in Brazil

open access: yesGreenhouse Gases: Science and Technology, EarlyView.
ABSTRACT As Brazil moves toward implementing its decarbonization commitments, carbon capture and storage (CCS) hubs are emerging as a key pathway for large‐scale CO2 abatement in hard‐to‐abate sectors. This paper presents a multifactorial, data‐driven framework to screen and prioritize potential CCS industrial clusters and hubs across Brazilian regions,
