Scientists in the United States claim to have proven the existence of an atomic-scale phenomenon in a perovskite material. Using powerful, ultra-fast bursts of light, the group was able to capture images of the ‘Rashba effects’ within the material. The researchers say the phenomenon could be harnessed to create new opportunities for PV and other perovskite-based devices.
As part of its research into organometal halide perovskites, the U.S Department of Energy’s Ames Laboratory has developed a spectroscopic technique which it says can ‘capture the moment, less than one trillionth of a second, where a particle of light hits a solar cell and becomes energy.’
This is the first time that U.S. wind and solar have met more than 10% of demand in a single month; however individual states led by California and Iowa have reached much higher penetrations.
