Multiple Synergistic Effects Enabling Efficient Kesterite Solar Cells via Introducing a Cu2O‐Bi2O3 Sacrificial Interlayer

open access: yesCarbon Energy, EarlyView.
The Cu2O‐Bi2O3 thin film as a sacrificial interlayer at the back contact of kesterite solar cells achieves multiple synergistic optimizations in bulk defects, interface defects, back‐contact band offset, and MoSe2 properties. This enhances carrier separation, suppresses interface recombination, and enables DMSO‐processed kesterite devices to reach a ...

Buried Interface Engineering via a Bifunctional Guanidino‐Carboxyl Molecular Bridge for Enhanced Performance and Stability in Perovskite Solar Cells

open access: yesEcoEnergy, EarlyView.
A bifunctional molecular bridge using 4‐guanidinobutanoic acid (GCC) is constructed to comprehensively tailor the buried interface of PSCs. By passivating oxygen vacancies, optimizing energy‐level matching, and regulating perovskite crystallization, this strategy simultaneously boosts the power conversion efficiency to 25.37% (20.01% for 13.4 cm2) and ...

Nitrogen‐Site Isomerism Unlocks Exciton Dissociation in Vinylene‐Linked COF‐Based Photocatalysts

open access: yesEcoEnergy, EarlyView.
Two regioisomeric vinylene‐linked covalent organic frameworks (COFs) constructed from diazine units with different nitrogen positions are developed for photocatalytic hydrogen evolution reaction (HER). Although structurally similar, the isomeric COFs exhibit distinct electron distribution and charge‐separation behaviors, leading to a more than twofold ...
