Regulating Phase Evolution and Crystallization Dynamics Enables Low Open‐Circuit Voltage Deficit in Wide‐Bandgap Cu2ZnSnS4 Solar Cells

open access: yesAdvanced Materials, EarlyView.
Bilayer composition‐modulated sulfurization (BCMS) regulates Cu redistribution in solution‐processed Cu2ZnSnS4, suppressing Cu2SnS3 and favoring the direct transformation pathway, while transforming the crystallization from surface‐dominated growth to a more synchronized process.

Spin Transport Across Interfaces With the Non‐Collinear Antiferromagnet Mn3Sn

open access: yesAdvanced Materials, EarlyView.
We study spin transport with Mn3Sn|Metal${\rm Mn}_3{\rm Sn}\vert{\rm Metal}$ heterostructures. For Mn3Sn|Pt${\rm Mn}_3{\rm Sn}\vert{\rm Pt}$ heterostructures, ultrafast spin current generation by optical pumping of Mn3Sn${\rm Mn}_3{\rm Sn}$ is explored, while for Mn3Sn|NiFe${\rm Mn}_3{\rm Sn}\vert{\rm NiFe}$ heterostructures, we probe the spin–charge ...

Bioinspired Mechanosensitive Organic Artificial Neuron With Programmable Excitatory and Inhibitory Responses via Nonlinear Mechano‐Electrochemical Coupling

open access: yesAdvanced Materials, EarlyView.
Organic artificial neurons couple mechanical deformation and ionic environments through nonlinear mechano‐electrochemical dynamics. Mechanical strain and electrolyte concentration reshape their nonlinear electrical characteristics, programming excitatory or inhibitory spiking responses that mimic mechanosensitive biological neurons and enable ...
