Integrated Photoelectrode and Electrolyte Engineering via Carbon Quantum Dots for Self‐Powered H2O/O2‐Mediated Portable Photoelectrochemical Cells

open access: yesAdvanced Science, EarlyView.
Surface‐charged N‐CQDs serve as both electrolyte additives and photocathode modifiers. Electrodeposited N‐CQDs on Cu2O form a stable composite, steering 4e− ORR toward water. A quasi‐solid electrolyte with N‐CQDs aids charge migration, electrode‐electrolyte interfacial compatibility and replenishes active sites.

Dual‐Wavelength Control of Charge Accumulation in Rubrene Microcrystals with Anisotropic Conductivity

open access: yesAdvanced Science, EarlyView.
Rubrene microcrystals, forming two distinct sector types, are investigated using photoemission electron spectroscopy. The two sectors exhibit a built‐in charge landscape, arising from anisotropic conductivities. Upon excitation with UV light, the diamond‐shaped sectors accumulate significant charge, whereas the triangular sectors remain essentially ...

Synergistic Interface Engineering via Buffer Layer and UVO Treatment for High‐Performance PbS Quantum Dot Near‐Infrared Photodiodes

open access: yesAdvanced Science, EarlyView.
A dual‐interface strategy combining a solvent‐orthogonal Poly‐TPD buffer with UV–ozone tuning of PbS‐EDT reconstructs interfacial energetics and defect chemistry in PbS CQD photodiodes. The optimized interface suppresses shunt‐ and trap‐related leakage, reduces noise, and enables high‐detectivity near‐infrared detection with imaging capability ...
