New research expected to improve laser devices and make photovoltaics more efficient
University of Chicago scientists have induced electrons in the nanocrystals of semiconductors to cool more slowly by forcing them into a smaller volume. This has the potential to improve satellite communications and the generation of solar power.
"Slowing down the cooling of these electronsin th...
Are photovoltaics a power supplement, full replacement or neither?
