Dual-Fuctional Semiconducting Polymer Blend System for Integrated Organic Electronic Device

Abstract

Unlike conventional silicon semiconductors, organic semiconductors are attracting attention as next-generation semiconductors due to their various advantages such as low cost, solution processability, flexibility and high transparency. Due to these various advantages, various organic electronic devices such as organic solar cells (OSC), organic field effect transistors (OFET) and organic light emitting diodes (OLED) are being researched. However, because of structural constraints and the complexity of the fabrication process, there are not many studies to simultaneously operate two or more devices. In this study, we simplified the complex structure of OFET and OLED integrated device by using solution process and polymer composites blend system (FET material: P29-DPP-TVT, LED material: PDY-132). In addition, OLED (Electroluminescence ~ 4200 cd / m2) was operated through OFET (Hole mobility ~ 0.29) in this integrated device. Moreover, various organic FETs (DPP2T-TT, PCDTPT) were applied to drive OLED-OFET integrated devices, thus suggesting the possibility of one platform technology of organic electronic devices.
