‘Movies’ of electron motion in solar cell made using femtosecond laser

“Movies” of electrons as they move across a semiconductor junction have been made by researchers at the Okinawa Institute of Science and Technology in Japan using a new imaging technique. Combining photoemission electron microscopy with femtosecond laser pump-probe methods, the technique tracks the motion of electrons on timescales shorter than 1 ps. The researchers say it could provide a better understanding of how semiconductor devices work and lead to more efficient solar cells….
