Electronic and optical absorption properties of organic-inorganic perovskites as influenced by different long-chain diamine molecules: first-principles calculations.

ABSTRACT: Organic-inorganic perovskites have demonstrated significant promise as photovoltaic materials due to their excellent photoelectric properties. However, monoamino three-dimensional (3D) perovskites, such as CH₃NH₃PbI₃ (MAPbI₃) and NH₂CHNH₂PbI₃ (FAPbI₃) exhibit low thermal and chemical stability, leading to low device durability. As such, we sought to address this problem by evaluating the performance of five diamino-3D perovskites with different molecule chain lengths, including NH₃(CH₂)₂NH₃PbI₄ (EDAPbI₄), NH₃(CH₂)₃NH₃PbI₄ (DPAPbI₄), NH₃(CH₂)₄
