Lead Performer: University of Michigan – Ann Arbor, MI
DOE Total Funding: $900,000
Cost Share: $225,269
Project Term: September 1, 2016 – February 28, 2019
Funding Opportunity: SSL R&D Funding Opportunity Announcement (FOA) (DE-FOA-0001364)

Project Objective

This project will develop innovative methods to outcouple the light within OLED devices in order to increase external quantum efficiency. This will be accomplished through nanoscale texturing beneath the anode outside the active region, fabricating sub-anode gratings along with microlens arrays, and top emitting structures with a sub-anode grid coupled with a reflective mirror at the base.

Project Impact

This project addresses the problem of how to reduce the amount of light that remains trapped in the OLED device. It will result in improved efficiency and longer lifetime.
