New Dication-Based Lead-Deficient 3D MAPbI₃ and FAPbI₃ "d-HPs" Perovskites with Enhanced Stability.

ABSTRACT: Toxicity induced by the presence of lead and the rather poor stability of halide perovskite semiconductors represent the major issues for their large-scale application. We previously reported a new family of lead- and iodide-deficient MAPbI₃ and FAPbI₃ perovskites called d-HPs (for lead- and iodide-deficient halide perovskites) based on two organic cations: hydroxyethylammonium HO-(CH₂)₂-NH₃⁺ (HEA⁺) and thioethylammonium HS-(CH₂)₂-NH₃⁺ (TEA⁺). In this article, we report the use of an organic dication, 2-hydroxypropane-1,3-diaminium (2-propanol 1,3 diammonium), named PDA²⁺, to create new 3D d-HPs based on the MAPbI₃ and FAPbI₃ n
