PROJECT OBJECTIVE

This project seeks to develop low-cost, scalable, ultrahigh-conductive, transparent, single-walled carbon nanotube films fabricated on low-surface-roughness, high-light-extraction-efficiency, flexible polymer substrates for high-efficiency OLED lighting. The target is to demonstrate white OLEDs with an external quantum efficiency of 60% and efficacy of 150 lm/W, without the use of any additional light-extraction structures. The technical benefits from creating carbon nanotubes are important for moving beyond rare earth metals and other environmentally unsustainable materials being used in LEDs and OLEDs. The economic benefits for reducing the costs of OLEDs are important for improving the position of OLEDs in the marketplace.

PROJECT IMPACT

Achieving the project’s goals will help streamline and reduce the fabrication costs of OLEDs by removing the indium tin oxide process, and will help reduce the lighting industry’s dependence on rare earth metals and other environmentally unsustainable materials.
