DOE Total Funding: $150,000
Project Term: July 2, 2018 – April 1, 2019
Grant Type: SBIR

PROJECT OBJECTIVE

In this project, InnoSense, in collaboration with the University of Virginia, proposes to develop a transparent conductive oxide (TCO) using a composite matrix of carbon nanotubes (CNTs), graphene oxide (GO), and aluminum doped zinc oxide (AZO) nanoparticles (NPs). The high conductivity of CNTs and AZO and further p-doping to CNTs by GO will ensure low sheet resistance. The low optical absorption of CNTs and GO, combined with the low thickness of the thin film, contribute to high transmittance at visible light wavelengths.

PROJECT IMPACT

The resulting film, called “nanomaterials-enabled” TCO, will have low sheet resistance (<1 Ohm/sq as a final goal) and high transmittance (≥90%), which makes it suitable as an OLED anode with the additional advantages of superior flexibility on plastic or other soft substrate, long-term stability, and inherent compatibility with candidate OLED manufacturing methods, such as roll-to-roll or spray casting for large-size film fabrication. While the proposed material has potential applications in many product areas of EERE interest, such as displays and photovoltaics, the effort under this project will focus on OLEDs, specifically anodes as an alternative to the present use of indium tin oxide.
