Fast Nanoscale Movies Shed Light on a Solar Cell Mystery

The perovskite solar cell is a photovoltaic wunderkind. Only a decade old, this next-generation solar technology is already hitting efficiency milestones that took conventional silicon solar cells nearly half a century to achieve. The cells are made from a class of materials called perovskite whose properties enable thin, flexible solar cells that can be printed like ink on the cheap. In principle, perovskite cells could turn everything into a solar panel—your car, your windows, even your clothes. But before perovskite can dethrone silicon as the king of solar semiconductors, researchers…
