Climate Crisis, Human Mobility and Security Challenges in the MENA Region: Implications for Sustainable Development and Regional Stability

Sustainable Development, EarlyView.
ABSTRACT This study examines the interplay between climate change, violent conflict and forced migration in the Middle East and North Africa (MENA), focusing on asylum flows to the European Union (EU). By integrating high‐resolution climate, conflict and socioeconomic data spanning 2000 to 2023, we develop a comprehensive empirical framework to ...

The Role of Interfacial Energetics and Defects on The Efficiency of Tin Perovskite Solar Cells

Small, EarlyView.
ABSTRACT Tin perovskites are emerging as a sustainable alternative to lead‐based photovoltaics, yet their efficiency remains limited by energy‐level mismatch and intrinsic instability from tin oxidation. Progress is further hindered by inconsistent electrical behavior, obscuring the true bottlenecks of device performance.

Stoichiometry‐Driven Interdependencies in PECVD a‐SiNx:H Films: Linking Hydrogen Behavior, Optical Properties, and c‐Si Solar Cell Performance

Small, EarlyView.
Stoichiometry control in PECVD a‐SiNx:H films governs hydrogen bonding, film mass density, optical response, and metallization‐induced shunting in crystalline silicon solar cells. Balanced SiH4/NH3 flow defines a practical processing window that improves passivation while limiting reflection, absorption, and Ag‐related leakage.

Loss Analysis of Low Bandgap (Ag,Cu)(In,Ga)Se2 Solar Cells for Tandem Applications

Small, EarlyView.
A complete loss analysis has been carried out on the state‐of‐the‐art 1.0 eV bandgap (Ag,Cu)(In,Ga)Se2 solar cells, which are of interest for tandem devices. The most significant loss mechanisms are found in the open‐circuit voltage, due to non‐radiative losses in the chalcopyrite absorber, and in the fill factor, caused by space‐charge region ...
