Formation of cubic perovskite alloy containing the ammonium cation of 2D perovskite for high performance solar cells with improved stability.

ABSTRACT: The perovskite solar cells have demonstrated to be strong competitors for conventional silicon solar cells due to their remarkable power conversion efficiency. However, their structural instability is the biggest obstacle to commercialization. To address these issues, we prepared (CH₃NH₃)_1-x (HC(NH₂)₂) _x PbI₃ (CH₃NH₃ = MA, HC(NH₂)₂ = FA) perovskite alloys that contain ethylammonium (EA, CH₃CH₂NH₃ ⁺) and benzylammonium (BA, C₆H₅CH₂NH₃ ⁺) cations with no new additional two-dimensional (2D) perovskite phases. The crystal structures of alloy perovskites exhibit th
