Over Tenfold Increase in Current Amplification Due to Anisotropic Polymer Chain Alignment in Organic Electrochemical Transistors

open access: yesAdvanced Materials, EarlyView.
How to boost the IDS output of an OECT? Anisotropic polymer alignment along the channel direction enables a 13‐fold increase in IDS. Such channel engineering opens the door to unprecedented signal amplification (here gmL/Wd = 2 580 S cm−1 with a PBTTT‐backbone bearing single‐ether side chains), faster ON/OFF switching, and improved stability for the ...

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.

Uni‐Axial Densification of Slurry‐Casted Li₆PS₅Cl Tapes: The Role of Particle Size Distribution and Densification Pressure

open access: yesAdvanced Materials, EarlyView.
Solid‐state batteries promise high energy density and safety for electric vehicles. This study examines the densification of slurry‐casted Li₆PS₅Cl separator tapes, highlighting the role of particle size distribution and uni‐axial pressure. Wet milling refines particles while preserving conductivity, and a critical compaction threshold leads to ...

Electrospun Lignin/ZnO Nanofibrous Membranes for Self‐Powered Ultrasensitive Flexible Airflow Sensor and Wearable Device

open access: yesAdvanced Materials, EarlyView.
This study explores the novel sensing applications of water evaporation‐induced power generation, by using lignin/ZnO nanofibrous membranes for sensing airflow through output voltage variation. Obtained lignin/ZnO airflow sensors are self‐powered, precise, and quick‐responding, and can be used as wearable devices for breath monitor, surrounding ...
