Nonvolatile chlorinated additives adversely influence CH3NH3PbI3 based planar solar cells

Abstract

We demonstrate that nonvolatile CaCl2 additives can significantly improve the film morphology of CH3NH3PbI3. Unlike those volatile chlorinated additives, a small portion of Cl anions from CaCl2 seem to enter into the CH3NH3PbI3 crystal, yet most insulating CaCl2 remains within the perovskite film, which is detrimental to perovskite solar cells.
