Beyond Earth: Resilience of Quasi‐2D Perovskite Solar Cells in Space

open access: yesAdvanced Materials, EarlyView.
In the article (DOI: 10.1002/adma.202520433), Christoph Putz and co‐workers demonstrate rigid quasi‐2D perovskite solar cells operating in low Earth orbit, delivering stable power for more than 100 days under real‐space conditions. In‐orbit performance is correlated with extensive ground‐based thermal and proton‐irradiation studies on rigid and ...

Strain‐Driven Surface Reconstruction During the Alkaline Oxygen Evolution Reaction: a Model Thin‐Film Study

open access: yesAdvanced Materials, EarlyView.
ABSTRACT Dynamic surface reconstruction critically governs the performance and durability of oxide‐based electrocatalysts for the oxygen evolution reaction (OER), yet controlling this process under operating conditions remains challenging. Here, we demonstrate that lattice strain regulates the extent of surface reconstruction in perovskite oxides by ...

Entropy‐Driven Spin Transition in Rare Earth Perovskites Enables Feedback Adsorption for Enhanced Acidic Water Oxidation

open access: yesAdvanced Materials, EarlyView.
A synthetic protocol for fabricating high‐entropy rare earth perovskite oxides with abundant lattice distortions and oxygen vacancies has been developed, representing an emerging platform for anchoring RuO2. High entropy strategy significantly modulated the electronic structures and spin states, inducing a shift in the mechanism from the adsorption ...
