Organic light emitting devices are bright and efficient but the conductive electrodes absorb all waveguided light. In this project we will realize narrow OLEDs with lateral electrode and hole transport in order to separate the conductive electrodes from the light emitting recombination region.
The light will be captured in a waveguide to reach large intensities and possibly lasing.
Organic and perovskite-based materials promise disruption to the field of thin film optoelectronics, owing to their advantages of low-cost, lightweight, flexibility, and spectral tuning compared to tradition solid-state bulk electronics. However, the high power conversion efficiencies of thin film photovoltaics (12% for organic and 22% for perovskite-based) and some high resolution organic light emitting diodes (OLEDs) displays are developed ...
The interest in metal halide perovskites soared in the past few years due to their immense potential in light-harvesting and generations through low-cost, scalable, solution-processed and facile device fabrication techniques. In addition to the prominent photovoltaics research, the light-emitting devices using perovskites shows strong promises with high external quantum efficiencies (>20%). However, there are several fundamental issues ...
Producing light with low energy consumption and low production costs is of vital importance for both the display and lighting industries and also to exploit energy resources more efficiently. The goal of BLOLEDs is to attain long-lasting and highly-performant blue organic-light emitting diodes (OLEDs) thanks to the help of state-of-the-art first principles tools. In contrast to red or green OLEDs, the fabrication of a highly-efficient blue ...
In my dissertation, I introduce different types of anisotropy to Organic Light Emitting Diodes (OLED) and demonstrate how these can be used to increase the efficiency of the device. A material is anisotropic when it has a physical property
that has a different value when measured in different directions. OLED devices are a type of Solid State Lighting (SSL) which consist, for the most part, of amorphous organic semiconductors. OLEDs have ...
