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

open access: yesAdvanced 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.

Main‐Chain Ion‐Pair Polybenzimidazole Membranes Enabling Reduced‐Temperature HT‐PEMFC Operation (Down to 120°C)

open access: yesAdvanced Energy Materials, EarlyView.
Embedding imidazolium‐biphosphate ion pairs directly into the polybenzimidazole main chain simultaneously stabilizes phosphoric acid and preserves continuous proton transport pathways. Strong ion‐pair and hydrogen‐bond interactions suppress acid leaching while maintaining high conductivity, enabling stable and durable high‐temperature fuel cell ...

Understanding the ADR premium under market segmentation. [PDF]

open access: yes
Capital controls can induce large and persistent deviations from the Law of One Price for cross-listed stocks in international capital markets. A considerable literature has explored firm-specific factors which influence ADR pricing when LOP is violated.

High‐Performance Noble‐Metal‐Free Perovskite Solar Cells Enabled by MoOX/Cr/Al Multilayer Electrodes

open access: yesAdvanced Energy Materials, EarlyView.
Cost‐effective perovskite solar cells (PSCs) are developed using a noble‐metal‐free MoOX/Cr/Al multilayer electrode. The devices achieve a power conversion efficiency (PCE) of 25.6%, competitive with that of Au‐based devices (26.3%), and a 25.5 cm2 mini‐module shows 21.3% PCE.
