Getting two for one: 'Bonus' electrons in germanium nanocrystals can lead to better solar cells

Saturday, February 14, 2015 - 00:00 in Physics & Chemistry

Researchers from FOM, the University of Amsterdam, the Delft University of Technology and the University of the Algarve have discovered that when light hits germanium nanocrystals, the crystals produce 'bonus electrons'. These additional electrons could increase the yield of solar cells and improve the sensitivity of photodetectors. The researchers will publish their work in Light: Science & Applications today.
