Excitonic Harvestation Radiative Recombination by Analysis and Comparison of the Experimental Data Measurements and the Theoretical Data Calculations from Silvaco-TCAD

Abstract

Organic Light Emitting Diodes (OLEDs) have developed to show many advantageous and noticeable properties including their flexibility, easy processing, very cost effective chemical technology, and easy combining of organic material, hence having optimized performance is very significant. Therefore, we have to find new methods in order to be able to use the total singlet and triplet excitons population and to achieve 100% internal efficiency. If we can extend the internal efficiency to 100%, this will lead to efficient production of OLEDs in the industry. In this work, to consider increasing excitons’ population, we have worked on the uniformity of the Electron Transport Layer (ETL) and Emissive Layer (EL) by applying argon atmosphere pressure cold jet plasma. Examining the experimental data in comparison with the theoretical data has shown us that having a better uniformity in barriers (based on AFM images) and decreasing contact angle will lead to a better injection and more exciton's population leading to an increase in the internal efficiency.
