Biomaterials based HTL for Organic Light Emitting Diode

Résumé

There is an increasing demand for compact, efficient and biocompatible Organic Light Emitting Diode (OLED). More particularly biophotonic applications like imaging, investigating, treating living matter by the use of light require a high level of integration with high efficiency. OLED technology is mature enough to fulfill these requirements, but some applications like optogenetics, therapy, lab on chip require also the use of biocompatible materials (bioresorbable materials may be desirable in some cases). Moreover, biomolecules integration within OLEDs contributes to diminish component embedded energy and therefore its carbon footprint. Nevertheless, biomaterials-based OLED is a challenge in order to achieve performance requirements, to find suitable fabrication process compatible with their properties and to overcome limitations due to their stability and durability. In this context, this paper is focused on the integration of biomolecules-based Hole Transport Layer within OLED. More particularly we focused on carotenoid materials which exhibit suitable electrical properties to be used as HTL for OLED. This work is part of a collaboration between ISIMM in Tunisia and the LAPLACE laboratory in Toulouse. This study includes DFT (density functional Theory) quantum modeling in order determine structural properties of carotenoids used in this work. Then ATLAS SILVACO TCAD was used to perform numerical modeling of the elaborated structure, and the resulting I-V characteristic was compared to experimental results. Finally, the structure has been optimized in order to achieve the best possible performances.
