a Natural crystallization process of Sn–Pb perovskite intermediate phases without (Pristine) and with DPSO modulation (DPSO). b Oxidation of SnI2 solution (dissolved in DMF) without and with DPSO. c In-situ UV–vis absorption spectra of SnI2 solutions at a concentration of 1 mM. XPS spectra of Sn 3d of d pristine, and e DPSO-modulated Sn–Pb perovskite films. f DLS of perovskite precursor solutions
