solid state lighting & energy center

The Solid State Lighting and Energy Center (SSLEC) is focused on new semiconductor based technologies for energy efficient lighting and displays, power electronics, and solar energy conversion. The objective of the SSLEC is to provide a forum for its members - key industry partners and the faculty and student researchers at the University of California, Santa Barbara - to work in collaboration and across scientific disciplines to address the most challenging problems in these important and timely areas of research.

Electrical power is used inefficiently in cell phones, computers, appliances, automobiles, industrial equipment, and power distribution systems account for a tremendous waste of energy. New transistors based on gallium nitride (GaN) and related alloys offer a route to cut this waste significantly, providing energy savings compared to those expected from solid state lighting. Researchers in the SSLEC pioneered GaN based power transistors and continue to lead the world with new discoveries and inventions.

Through basic and applied research intimately tied to industrial goals, the members of the SSLEC will maintain their leadership in increasingly energy sensitive markets. The center boasts over 100 patents since 2007.

  • Lighting the World: Shuji Nakamura and His Brilliant Discovery

    About this series: We take light for granted, but more than two billion people in the world go through their entire lives without reliable lighting. But that is changing, thanks in part to the brilliant discovery of UC Santa Barbara's Shuji Nakamura. This four-part series, made possible by UC Santa Barbara's Solid State Lighting and Energy Center, tells the story of Nakamura's determined effort to develop the white LED and the revolution in lighting that his discovery has brought to the world.

    UCSB's materials graduate program was ranked number two in the 2014 U.S. News list of American universities, and number one among public institutions. UCSB shares the number two ranking with Stanford University, while the top spot is held by Massachusetts Institute of Technology. Both MIT and Stanford are private research universities.
    In addition, UCSB's College of Engineering was ranked number 20, moving up one spot from the 2013 rankings. Tied with Northwestern University, it is number 11 among public universities.

(Top photo) Professor Shuji Nakamura is the recipient of the 2006 Millennium Technology Prize for his invention of the revolutionary new energy-saving light sources. Professor Nakamura astonished the scientific community with the first successful blue light-emitting diode (LED). The blue LED was the last step in the creation of the brilliant white LED, and ultra-efficient successor to Thomas Edison's incandescent light bulb of 1879.
