Perovskite Extended Structure and Film

Caption

At left: The SLAC study looked at atomic motions in a perovskite solar cell material made of lead (black spheres), iodine (purple) and methylammonium (red and blue). The atomic arrangement is typical for all perovskites, named after a naturally occurring mineral of titanium, oxygen and calcium. At right: Scanning electron microscope image of a thin perovskite film used in the study, showing grains of the material with a size of 50 to 100 nanometers.
