TL;DR: An ideal electrode structure based on a synergetic interplay of high-index TiO2 layers and low-index hole-injection layers sandwiching graphene electrodes is proposed, which results in an ideal situation where enhancement by cavity resonance is maximized yet loss to surface plasmon polariton is mitigated.

TL;DR: A novel anode structure based on micropatterned ITOs coated with high-conductivity (HC)-grade poly(3,4ethylenedioxythiophene): poly(styrene sulfonate) (PEDOT:PSS) layers is introduced to improve the outcoupling efficiency of OLEDs in a relatively simple way.

TL;DR: In this paper, the optical properties of a dielec-tric−metal−dielectric multilayer for the transparent top cathode in top-emitting organic light emitting diodes (TOLEDs) were investigated.

TL;DR: This work exploits the design freedom offered by organic technologies to realize a reflective patch-type pulse oximetry sensor with ultralow power consumption and demonstrates that organic devices not only have form factor advantages for such applications but also hold great promise as enablers for all-day wearable health monitoring systems.

TL;DR: In this article, organic solar cells based on pentacene/C60 heterojunctions were encapsulated using a 200nm-thick film of Al2O3 deposited by atomic layer deposition (ALD).
