Interfacial Engineering and Defect Passivation via Naphthalene Disulfonate-Modified NiOx to Improve the Stability of Perovskite Light-Emitting Diodes
{{output}}
NiOx is an inorganic hole layer that is widely used in perovskite light-emitting diodes (PeLEDs). However, direct interfacial contact with the perovskite film induces severe photoluminescence quenching, and buried interface defects critically impede the PeLEDs... ...
