This study investigates a hybrid lamination electrode based on a silver nanowire and a conductive polymer for the top electrode of bi-directional polymer light-emitting diodes (PLEDs). Through a vacuum-free hot-press lamination step, the proposed hybrid electrode employed a complete and concrete electrical contact with the underlying emissive polymer layer. In addition, by inserting a hole injec..

Yejin Kim (김예진, 18학번, 전남대) has joined our research group as a master degree student. She has been studying the fully vacuum-free fabrication of polymer light-emitting diodes by utilizing hybrid lamination electrodes. She will become an expert in the field of electroluminescence device based on emerging materials like quantum dots and perovskites. as well.

Fully vacuum-free manufacturing could be achieved from a silver nanowire and conductive polymer-based transparent lamination top electrode, thereby achieving complete and concrete electrical contact with the underlying polymer bulk-heterojunction layer through a simple hot-press lamination step. In addition, for the insertion of an appropriate hole-extracting interlayer between the lamination el..

Using “fully vacuum-free” and “solution-process” fabrication This research has been conducted by UROP (Undergraduate Research Opportunities Program) in JNU and Capstone Design class in 2021. This is the first step. And we are going to achieve highly effieicnt OLEDs with great cost-effectiveness within this year !!

Resistive random-access memory (RRAM) has been widely considered for its prospective applicability owing to its non-volatile characteristics. In this study, a polymer-based vacuum-free RRAM device fabricated with the conductive polymer, poly(3,4-ethylene-dioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS) was proposed. Pristine PEDOT:PSS coated on indium tin oxide (ITO) electrode was used as the ..

A silver nanowire (AgNW)-based stacked lamination electrode was investigated for application as the top electrode in fully vacuum-free and solution-processed organic photovoltaic (OPV) fabrication. AgNW layers were stacked with an ethylene-glycol-doped poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS) layer for conductivity enhancement and uniform contact creation, and an ethyl..
