The U.S. Department of Energy (DOE) has announced the competitive selection of nine projects for solid-state lighting (SSL), in response to its SSL R&D funding opportunity announcement (FOA) DE-FOA-0001364. The projects, which will span an 18 to 24-month period, will focus on the areas of Core Technology Research. This involves the application of fundamental scientific concepts to SSL technology; Product Development, which incorporates basic or applied research to develop or improve commercially viable SSL materials, devices, or systems; and Manufacturing Research and Development, which accelerates SSL technology adoption through manufacturing innovations and improvements that reduce costs and enhance quality and consistency. Funding for the nine projects translates to more than $10.5 million and leverages a cost-share contribution from each recipient, bringing the total public-private investment to more than $13.5 million.
This is the eleventh round of the DOE investments in SSL core technology research and product development. No manufacturing projects were selected in this 11th round. This program is part of the DOE's ongoing initiatives to promote the adoption of SSL technology. The project selections are listed below (final details are subject to negotiations):

Recipient: Lumileds, San Jose, Calif.
Project Title: High-Efficacy High-Power LED for Directional Applications
Summary: This project will develop a high-efficacy, high-power LED emitter enabled by patterned sapphire substrate flip-chip architecture, die development to include novel contact design, phosphors with reduced bandwidth, and new optical materials for light extraction from the die.
DOE Share: $1,498,228; Cost Share: $499,410
Recipient: North Carolina State University, Raleigh, N.C.
Project Title: Low Cost Corrugated Substrates for High Efficiency OLEDs
Summary: This project will develop OLEDs fabricated on low-cost high index corrugated substrates with a semi-random periodicity to give enhancements in extraction efficiency across the entire visible spectrum, due to the extraction of the thin-film-guided and surface-plasmon modes.

Recipient: Pennsylvania State University, State College, Pa.
Project Title: Understanding, Predicting, and Mitigating Catastrophic Shorts for Improved OLED Lighting Panel Reliability
Summary: This project will develop a way to better understand and predict the occurrence of short circuits in OLED lighting panels, in order to reduce failure rates by means of new, more-informative panel diagnostics, a modeling capability to predict mean time to failure, and new anti-shorting strategies that address the root cause of the problem.
DOE Share: $1,087,981; Cost Share: $271,996
Recipient: University of Michigan, Ann Arbor, Mich.
Project Title: Getting All the Light Out: Eliminating Plasmon Losses in High Efficiency White Organic Light Emitting Devices for Lighting Applications
Summary: 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 micro-lens arrays, and top emitting structures with a sub-anode grid coupled with a reflective mirror at the base.
DOE Share: $900,000; Cost Share: $225,269
