New Discovery Settles Debate About Photovoltaic Materials

Ames Laboratory scientists discovered evidence of the Rashba effect by using extremely strong and powerful bursts of light firing at trillions of cycles per second to switch on or synchronize a "beat" of quantum motion within a material sample; and a second burst of light to "listen" to the beats, triggering an ultrafast receiver to record images of the oscillating state of matter.

Scientists have theorized that organometallic halide perovskites-- a class of light harvesting "wonder" materials for applications in solar cells and quantum electronics-- are so promising due to an unseen yet highly controversial mechanism called the Rashba effect.
