High-speed surveillance in solar cells catches recombination red-handed
(PHYSorg.com Physics)

A research team at Osaka University has developed an improved method for producing microscope images that can spot speedy electrons zipping through nanomaterials used in solar panels. By applying laser light to the device at just the right times, this group achieved nanosecond time resolution for the first time while maintaining the magnification. This work could improve the quality of photovoltaic materials for devices such as solar panels by helping to identify and eliminate inefficiencies during the manufacturing process.
