The Role of Current Mismatch on Reverse‐Bias Stability of Monolithic Perovskite/Silicon Tandem Solar Cells

open access: yesEcoEnergy, EarlyView.
Reverse‐bias stability in monolithic perovskite/silicon tandem solar cells requires a silicon–current‐limited regime. When the perovskite current exceeds the silicon current, the reverse voltage is mainly borne by the silicon cell, reducing perovskite stress.

Monodisperse High‐Entropy Metal Oxide Nanoparticles Encapsulated Within 2D Porous Carbon Sheets for Enhanced Catalytic Activity in Lithium–Sulfur Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study synthesizes monodisperse oxide nanoparticles with abundant ionic vacancies encapsulated in 2D porous carbon sheets via pyrolysis of a high‐entropy precursor, constructing a cross‐scale catalytic interface. It enables Li‐S batteries with a high capacity of 761 mAh g−1 at 3 C and retains 80.44% capacity after 1000 cycles at 1 C.

Comprehensive Analysis of the Degradation Phenomena of Proton Exchange Membrane Water Electrolyzers with Iridium on Antimony Tin Oxide Anodes

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study examines the structural and chemical evolution of low‐loaded Ir/ATO anodes during PEM water electrolysis under realistic conditions. Iridium dissolution is largely suppressed. In the early stages, both ionomer and support degradation are detected. Morphological reorganization occurs at the interface between the anode catalyst layer (ACL) and
