- 摘要：Industrialization of perovskite solar cells is constrained by adverse stability in the air. Herein, we report effective strontium chloride (SrCl2) passivation upon HC(NH2)2−CH3NH3 (FA−MA)-based perovskite thin films for the suppression of nonradiative recombination. Moreover, the recombination dynamics, crystallinity, carrier transport, morphology, and the elemental stoichiometry of this film were systematically studied. By optimizing the concentration of SrCl2, the corresponding devices exhibited an increased open-circuitvoltage (1.00 V vs 1.09 V), consistent with the enhanced photoluminescen
