Unveiling Energy Loss Mechanisms to Empower Ternary Organic Solar Cells with over 20% Efficiency: A Systematic Oligomeric Approach

open access: yesAdvanced Materials, EarlyView.
This study designs modular oligomeric donors (5BDD, 5BDD‐F, 5BDT‐F, 5BDT‐Cl) for ternary OSCs, achieving PCEs >20%. By systematically tuning energy levels, we reveal material compatibility, not HOMO alignment, drive VOC enhancement, suppress ACQ and reduce energy loss, offering new design principles for high‐efficiency OSCs.

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 ...

Designing Physical Unclonable Functions From Optically Active Materials

open access: yesAdvanced Materials, EarlyView.
Assigning unforgeable “fingerprints” to manufactured goods is a key strategy to fight global counterfeiting. Optical physical unclonable functions (PUFs) are chemically generated random patterns of optically active materials serving as unique authenticators.

Advanced Electrode Materials for Efficient Hydrogen Production in Protonic Ceramic Electrolysis Cells

open access: yesAdvanced Materials, EarlyView.
Protonic ceramic electrolysis cells (PCECs) are a promising intermediate‐temperature hydrogen production technology, leveraging high proton conductivity in electrolytes yet constrained by insufficient catalytic activity and interfacial instability in fuel/air electrodes. This review systematically categorizes advanced electrode materials and critically
