摘要: With the unusual luminescence and photoconductive characteristics, the CsPbI 3 perovskite has attracted a lot of attention in the field of material synthesis and device fabrication. The general synthesis methods of CsPbI 3 are through the organic solvent spin-coating and heating. To avoid the toxic organic solvent, herein we reported the organic solvent-free synthesis method. The precursors PbI 2 and CsI were solved in aqueous solution and heated to form the CsPbI 3 perovskite. It is found that the Na 2 S 2 O 3 as a reaction additive …
