Transient Charging Dynamics in Stacked Ga2O3/ZnO Photovoltaic Units Governing Wavelength‐Selective Polarity Switching

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work reveals a “Photovoltaic‐Capacitance” coupling mechanism in stacked Ga2O3/ZnO devices, defining the ZnO/graphene interface as a novel Photovoltaic Dynamic‐Capacitor (PDC). The wavelength‐selective bipolar response enables a physical layer secure communication protocol based on ternary optical logic (“1,” “0,” “−1”).

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.

CO2 Conversion Into Energy Rich Fuels Over Nascent COF Decorated‐Lead Free Halide Perovskites Hybrid Nano Catalysts: Experimental and Computational Investigation

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A panoramic scheme signifies the CO2 conversion into energy‐rich fuels over nascent COF‐decorated lead‐free halide perovskite hybrid nano‐catalysts. Even though lead‐containing halide perovskites have been deemed emerging materials. However, the presence of toxic and carcinogenic lead (Pb) metal, small surface area, low charge separation, and a high ...

A Co‐Self‐Assembled Monolayer With Enhanced Coverage and Defect Passivation for Efficient Inverted Perovskite Solar Cells

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study achieved a co‐self‐assembled monolayer (Co‐SAM) with more uniform coverage on nickel oxide substrates and enhanced passivation of buried interfaces by incorporating 4PABCz into Me‐4PACz. Perovskite solar cells fabricated with this Co‐SAM achieved an efficiency of 26.33% and exhibited enhanced stability. The combination of nickel oxide (NiOx)

Atomic‐Scale Structurally Locked 1T/2H‐MoS2/ZnS Z‐Scheme Heterojunctions for Prolonged Charge Kinetics and Dual‐Functional Photocatalysis

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Atomic‐scale structurally locked 1T/2H‐MoS2/ZnS direct Z‐scheme heterojunction enabling dual‐functional photocatalysis. The metallic 1T‐MoS2 phase serves as an electronic actuator that bridges charge transfer across the heterointerface, resulting in prolonged charge kinetics, efficient hydrogen evolution, and complete degradation of Malachite Green ...
