Liquid-like motion in crystals could explain their promising behavior in solar cells
Scientists captured the average positions of the atoms in a perovskite crystal at different temperatures. They found that each lead atom and its surrounding cage of bromine atoms form rigid units that behave like molecules. These units oscillate - or jiggle back and forth - in a liquid-like manner.
