Can the latest technology, such as solar cells, be improved? An international research team led by the University of Gotingen is helping finding answers to such questions with a new technology. For the first time, the formation of small, hard-to-detect particles-which is known as dark exciton-can be tracked in the place and location. These invisible carriers of energy will play an important role in future solar cells, LEDs and detectors. The results are published in nature photonics.
