Cutting through noise for better solar cells

U physicists analyzed electrical noise to detect formerly invisible inefficiencies in solar cells and identified the physical processes that caused them. The technique could make future solar cells more efficient.

New perovskite LED emits a circularly polarized glow

LEDs led to the high-definition viewing experience we’ve come to expect from our screens. A new type of LED that utilizes spintronics could take displays to the next level.

Gerald Stringfellow’s bright idea

The legacy of the U’s mastermind behind LED-based technology was honored in a video from the National Academy of Inventors.


FROM BREAD TO BULB

Two U researchers have found a way to create LEDs from tortillas and soda.
