Abstract

Herein, strong oxidants are employed for the first time to stabilize the main frame structure of the perovskite [PbI₆]⁴⁻ by strengthening the interaction between the central Pb atom and coordination I atoms. A systematic study on the microstructure and macrostate of the perovskite is carried out by the synchrotron radiation technique and conventional characterization. According to the valence state and local environment of each chemical element, crystallinity and morphology of the active layer, and photoelectric properties of the solar cell, the strong oxidants, tris[2-((1H-pyrazol-1-yl)-4-tert-butylpyridine)cobalt(III)tris(bis(trifluoromethylsulfonyl)imide)] (FK209) and Na₂S₂O₈, can increase the power conversion efficiency and stability of the doped devices. A possible mechanism of doping strong oxidants is explained.
