Abstract
The micro-structural observation analysis of the perovskite layer with high resolution TEM is the most promising approach to understand the crystal structure. Recently we newly revealed that the tetragonal and cubic phases coexist at room temperature in the conventional MAPbI3 thin film device. Furthermore superlattices composed of these mixture of tetragonal and cubic planes without any compositional change was also found.
