Abstract

We have fabricated transparent inverted organic light-emitting diodes (OLEDs) using a metal mesh embedded conductive film (MEF) with a non-metal transparent conductor and a novel vacuum lamination method. The device with the proposed electrode exhibits higher transmittance, lower reflectance, and especially much more stable optical properties than those of the conventional OLEDs with thin metal top electrodes over an entire visible region. Moreover, lower driving voltage is also achieved due to the embedded metal mesh. We demonstrate its potential as a reliable transparent top electrode in various optoelectronic devices.
