Abstract

Material and functional stability remains a major issues in field of perovskite photovoltaics. To achieve a long device lifetime, it is crucial that we understand and optimize the lifetime of the material itself. One-step antisolvent processing is a facile method to enhance stability. Herein, we report that changes in the degradation process of perovskite films is modified by the antisolvent treatment in comparison to the conventional film without the process which we measure by monitoring the emission. Perovskite films prepared with anti-solvent processing have improved film morphology and reduced evolution of surface metallic lead, which correlated with improved film lifetimes.
