제목 Nanoparticle-Enhanced Silver Nanowire Plasmonic Electrodes for High-Performance Organic Optoelectronic Devices
초록 In this study, we demonstrate improved performance in plasmonic organic solar cells (OSCs) and organic light-emitting diodes (OLEDs) via strong plasmon coupling effects generated by aligned silver nanowire (AgNW) transparent electrodes decorated with core-shell silver-silica nanoparticles (Ag@SiO2NPs). NP-enhanced plasmonic AgNW (Ag@SiO2NP-AgNW) electrodes enable substantially enhanced radiative emission and light absorption efficiency due to strong hybridized plasmon coupling between localized surface plasmons (LSPs) and surface propagating plasmons (SPPs), which leads to improved device performance in organic optoelectronic devices. Notably, an electroluminescence efficiency of 25.33 cd/A (at 3.2 V) and a power efficiency of 25.14 lm/W (3.0 V) in OLEDs, as well as a power conversion efficiency value of 9.19% in OSCs are achieved using hybrid Ag@SiO2NP-AgNW films. These are the highest values reported to date for optoelectronic devices based on AgNW electrodes.
