Testing the performance of semiconductors—with light

Wednesday, March 29, 2017 - 08:02 in Physics & Chemistry

Semiconductors are the cornerstone of modern electronics. They're used in solar cells, light emitting diodes (LEDs), microprocessors in laptops and cell phones, and more. Most of them are made of silicon, but silicon has its limitations. So for decades researchers have been exploring new materials with properties that make them good candidates for better, lighter, and cheaper energy-efficient lamps, solar cells, and even – someday, perhaps – solar energy-harnessing "paint."
