Perovskite Crystallization Dynamics during Spin-Casting: An In Situ Wide-Angle X-ray Scattering Study.

ABSTRACT: In situ wide-angle X-ray scattering (WAXS) has been measured during the spin coating process used to make the precursor films required for the formation of thin films of perovskite. A customized hollow axis spin coater was developed to permit the scattered X-rays to be collected in transmission geometry during the deposition process. Spin coating is the technique most commonly used in laboratories to make thin perovskite films. The dynamics of spin-casting MAPbI_3-x Cl _x and FAPbI_3-x Cl _x films have been investigated and compared to investigate the differences between the dynamics of MAPbI_3-x Cl _x and FAPbI_3-x Cl _x film formation.
