Zinc Sulfide Enabling Remarkable Surface Passivation of Crystalline Silicon

Advanced Energy Materials, EarlyView.
Polycrystalline ZnS films capped by Al2O3 provide outstanding surface passivation performance. The excellent lattice agreement between c‐Si and ZnS combined with a hydrogenation step result in extremely low interface state density (≈ 1×1010 cm−2 eV−1) and recombination current pre‐factor (1.0 fA/cm2), revealing a new passivation strategy for ...

Positive Aging‐Free Quantum Dot Light‐Emitting Diodes Enabled by Single‐Source Chloride‐Doped ZnMgO Electron Transport Layers

Small, EarlyView.
Single‐source chloride doping of ZnMgO electron‐transport layers (ETLs) intrinsically suppresses oxygen‐vacancy traps, eliminating storage‐driven positive aging in quantum dot light‐emitting diodes. Devices deliver day‐0 peak external quantum efficiency and longer operational lifetimes, while transport and interfacial photoluminescence remain time ...
