DOE Announces Four SBIR/STTR Grants for SSL Technology

The U.S. Department of Energy (DOE) has awarded three Small Business Innovation Research (SBIR) grants and one Small Business Technology Transfer (STTR) grant targeting advances in solid-state lighting (SSL) technology. The SBIR/STTR program seeks to increase the participation of small businesses in federal R&D. To learn more about the DOE Office of Science SBIR/STTR program, visit

  • One Phase I award will explore the technical merit or feasibility of an innovative concept or technology.
  • Three Phase II awards will expand on Phase I results and enable the awardees to evaluate the commercial potential of new technology.

The Phase I award is briefly described below:

SBIR Recipient: Soraa Inc.
Title: Large-Area Semipolar Ammonothermal GaN Substrates for High-Power LEDs
Summary: This project seeks to develop a new, cost-effective manufacturing technology for large-area single crystal wafers of gallium nitride, the material on which white LEDs are based, with a unique orientation. If successful, the new technology will enable fabrication of low-cost, high-efficiency LEDs.

The Phase II awards are briefly described below:

SBIR Recipient: Universal Display Corp.
Title: Thermal Management of Phosphorescent Organic Light Emitting Devices
Summary: UDC will to continue to develop advancements to their thermal management of large-area OLED light panels based on the success of the Phase I effort. They will develop various approaches to improve the thermal management including building a physical model, establishing panel-level test methods, optimizing the panel layout, and exploring novel substrates and encapsulation systems, which, when applied to their phosphorescent OLED (PHOLED) technology, will enable a record low panel operating temperature of less than 30°C at 10,000 lm/m2.

SBIR Recipient: Advanced Cooling Technologies, Inc.
Title: Dielectric Printed Circuit Board Planar Thermosyphon
Summary: Thermal management has been identified as a critical obstacle along DOE's multi-year roadmap to ensure and accelerate the development and deployment of LED lighting products. The proposed passive heat spreader will dramatically improve the thermal management of high-brightness, light-emitting diodes without imposing significant costs. The unusual thermal management approach has been successfully applied to military electronics and promises a 50% improvement in chip level heat transfer compared to conventional heat pipe designs.

STTR Recipient: Sinmat Inc.
Title: Low Cost, Scalable Manufacturing of Microlens Engineered Substrates (MLES) for Enhanced Light Extraction in OLED Devices
Summary: The project objective is to develop a novel, low-cost method to create a microlens engineered substrate that is expected to show significant enhancement in outcoupling efficiency while simultaneously reducing manufacturing cost. Over 75% improvement in extraction efficiency is claimed based on patented concepts already under development. These improvements will yield a three-fold increase in the efficiency of organic light-emitting diodes.
