Harnessing Synergistic Cooperation of Neighboring Active Motifs in Heterogeneous Catalysts for Enhanced Catalytic Performance

open access: yesAdvanced Materials, EarlyView.
This review examines the critical role of neighboring active motifs in heterogeneous catalysts, emphasizing how their synergistic cooperativity can be rationally designed to modulate catalytic properties. The discussion centers on the modulation of electronic and geometric structures, categorizing the catalytic systems into metal‐acid (Brønsted/Lewis ...

Advancing Self‐Assembled Molecules Toward Interface‐Optimized Perovskite Solar Cells: from One to Two

open access: yesAdvanced Materials, EarlyView.
In the past few years, self‐assembled molecules (SAMs) have ushered in a new era of interface engineering for perovskite solar cells. Herein, the recent progresses of co‐SAM, namely two SAMs with synergy, are comprehensively summarized and analyzed, focusing on topics including deposition methods and design principles, while further challenges about ...

Revealing Trapped Carrier Dynamics at Buried Interfaces in Perovskite Solar Cells via Infrared‐Modulated Action Spectroscopy with Surface Photovoltage Detection

open access: yesAdvanced Materials, EarlyView.
A new spectroscopy technique (i.e., pump‐push‐surface photovoltage) is introduced that monitors trapped carrier dynamics at the buried interfaces in perovskite solar cells (PeSCs) via combining optical trap activation by infrared light with surface photovoltage detection.

Electron Extraction Optimization for Carbon‐Based Hole‐Conductor‐Free Perovskite Photovoltaics With Record 1.41 V VOC

open access: yesAdvanced Materials, EarlyView.
A gradient electron energy level strategy is constructed to reduce voltage losses in planar HTL‐free CsPbI2Br C‐PSCs. This electron extraction optimization enables rapid photogenerated electron extraction and carrier separation, thereby suppressing recombination at the back contact. The resulting PSCs deliver a record VOC of 1.41 V, a high PCE of 17.42%

Spectrally Engineered Coatings for Steering the Solar Photons

open access: yesAdvanced Materials, EarlyView.
Spectrum‐splitting energy synergy: a spectrally engineered radiative cooling (RC) coating with photoluminescence is integrated with bifacial photovoltaic (biPV) panels to construct a hybrid biPV‐RC system. By controlling solar photon conversion pathways and guiding light transport, the system enables synergistic power generation and daytime radiative ...

Unveiling the Aging Effect at the Interface of N719 Dye‐Sensitized Solar Cells

open access: yesAdvanced Materials Interfaces, EarlyView.
Iodide is incorporated into the N719 layer through two mechanisms: the known ligand exchange of NCS with I and a second yet unknown mechanism which significantly blocks the charge regeneration process of the N719 dye contributing to the cell degradation.

Modulating Polaron Behavior in PM6 Blends with Nonfullerene and Fullerene Acceptors: The Importance of Singlet Energy Transfer

open access: yesAdvanced Materials Interfaces, EarlyView.
Transient absorption spectroscopy is employed to demonstrate that nonfullerene acceptors inhibit the formation of bound polaron pairs in conjugated polymers, which would otherwise undergo rapid relaxation back to the ground state. Instead, efficient energy transfer from the polymer to the non‐fullerene acceptor takes place, facilitating high charge ...
