FlexMat, EarlyView.Integrating carbonyl lock onto multi‐resonant organoboron emitters is found to go beyond conventional bridge unit. It can not only suppress the molecular relaxation as conventional bridge, but also substantially affect electronic engineering via carbonyl integration, activating multiple up‐conversion channels, thus leading to an accelerated spin‐flip ...

Progress in Photovoltaics: Research and Applications, EarlyView.This work reveals that glass frit chemistry governs acetic‐acid‐induced corrosion and damp‐heat stability in LAF‐processed TOPCon modules. Compared with a Pb/B‐rich frit, a Ba/Zn‐modified frit preserves the Ag–Si interface, suppresses contact‐resistance increase and improves module reliability.
