Polyelectrolyte Layer as a Work Function Modifier for Transparent Electrodes Enabling Efficient Perovskite Solar Cells With Superior Low‐Light Performance

EcoEnergy, EarlyView.
Polyelectrolytes represent a low‐cost and effective platform for tailoring charge extraction interfaces in inverted perovskite solar cells (PSCs). In this work, we introduce a protonated polyethyleneimine (PEI) layer (pH = 2) between the ITO electrode and the PTAA hole transport layer to increase the apparent work function of ITO by 0.066 eV and reduce

Boosting CO2 Selective Electroreduction to CH4 With High Efficiency Over Oxygen‐Riched Cu‐CeO2 Catalyst by Constructing Heterointerface Built‐in Electric Field

EcoEnergy, EarlyView.
Defect‐rich Cu‐CeO2 heterojunction generates a strong built‐in electric field, accelerates directional electron transfer from CeO2 to Cu, and enables highly selective and efficient CO2 electroreduction to CH4. ABSTRACT Electrochemical CO2 reduction reaction (CO2RR) to CH4 offers a sustainable route for carbon neutrality, but it is hindered by sluggish ...

Magnetic Electrocatalysts Enabling a High‐Rate Capability in Lithium‐Oxygen Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study introduces zinc ferrite (ZnFe2O4) nanoparticles with tunable magnetic properties as bifunctional electrocatalysts for lithium‐oxygen batteries. Under an applied magnetic field, these catalysts significantly enhance oxygen reduction and evolution reactions by promoting spin‐aligned charge transfer and ion diffusion. The approach achieves high

Enhancing the Ferroelectricity of MAPbI3 via Hydroxyl Groups to Boost Photocatalytic Performance

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The hydroxyl groups in (EOA)2PbBr4 enable a rearrangement of the polar MA+ ions in MAPbI3, which enhances the Ps‐electric field and promotes the separation of photogenerated carriers. Consequently, the (EOA)2PbBr4/MAPbI3 composite exhibits the enhanced CO production yield in photocatalytic CO2 reduction reactions.
