This is the latest in a series of profiles of the MIT Energy Fellows — graduate students who are supported by MIT Energy Initiative (MITEI) members to participate in faculty-led research and become part of a long-term community of students and alumni. More information is at the MITEI Energy Fellowships site.
Grid-based lighting accounts for up to 20 percent of global electricity consumption, and more than half of U.S. residential lighting relies on incandescent lamps that leak about 95 percent of their input energy as heat.
To make a dent in the energy consumption and cost of solid-state lighting, Geoffrey J. Supran is helping develop quantum dot light-emitting diodes (QD-LEDs). Quantum dots are nanometer-sized, inorganic crystals that create light when stimulated with photons or electrons.
