Thanks to the ARPA-E OPEN, ICORLAB led by Prof. Can Bayram in the Department of Electrical and Computer Engineering will pursue direct-emitting novel green light emitting diodes (LEDs) that can enable accelerated solid-state lighting (SSL) adoption to reduce lighting-related energy needs and greenhouse gas emissions by approximately 25% compared to non-SSL. The transition to SSL could reduce U.S. energy needs and greenhouse gas emissions by an additional 55% by 2035 compared to non-SSL, accounting for 5% of the U.S.’ primary energy budget. High efficiency green LEDs enabled by cubic gallium nitride (GaN) is used to eliminate polarization and reduce droop, making them significantly more efficient than traditional III-V based LED technology. Our design could reduce manufacturing costs and facilitate widespread adoption of high efficient color-mixed SSL illumination by commercial and residential markets.
