Key Points

The aim is to evaluate and improve the power efficiency of organic light-emitting diodes using a hot-exciton-assisted exciplex system.
Analyzed the performance of organic light-emitting diodes (OLEDs) with a focus on power efficiency.
Compared hot-exciton-assisted exciplex to traditional systems.
Conducted experiments to evaluate photoelectric conversion efficiency.
The hot-exciton-assisted exciplex showed significantly higher power efficiency compared to conventional methods.
A reduction in injection barriers was observed, enhancing overall performance.
The findings suggest substantial improvements in OLED technology based on the HEAE system.

Abstract

Power efficiency (PE) is crucial for evaluating organic light-emitting diode (OLED) performance, as it directly reflects photoelectric conversion efficiency. Featuring a low injection barrier, exciplex shows greater potential than a...
