Spin‐On SiOx‐Assisted Inkjet Printing for Interdigitated n+ and p+ Poly‐Si/SiOx Contacts in Silicon Solar Cells With Suppressed Unintended Doping

open access: yesAdvanced Materials Technologies, EarlyView.
This work presents an innovative spin‐on SiOx‐assisted inkjet‐printed approach to form localized n+ and p+ poly‐Si/SiOx passivating contacts for high‐efficiency silicon solar cells within a single‐annealing step. The developed process results in a well‐defined interdigitated doping pattern, with unintended doping and cross‐doping concentrations ...

Enhancing Small Molecule Sensing With Aptameric Functionalized Nano Devices

open access: yesAdvanced Materials Technologies, EarlyView.
Unveiling an ultra‐sensitive, non‐invasive neurotransmitter sensor. For the first time, a nanoscale sensor for detecting an important neurotransmitter was demonstrated using micro‐electromechanical systems (MEMS) technology. Our approach utilized field‐effect transistor (FET)‐based readout to enable pico‐molar detection of biomarkers in sweat.

The Origin of Efficiency in III‐Nitride Micro‐Light‐Emitting Diodes

open access: yesAdvanced Science, Volume 13, Issue 25, 4 May 2026.
The images show panchromatic cathodoluminescence of III‐V materials, which reveal that AlGaInP red wafers, having fewer defects, support longer carrier diffusion lengths. Meanwhile, the density of defects increases with longer emission wavelengths in the InGaN system, illustrating how generated carriers pass through the material and how defects limit ...
