Abstract Different 2D and quasi-2D perovskite materials have demonstrated significant improvements in the device stability compared to 3D perovskites due their increased hydrophobicity suppressed ion migration. However, fundamental investigations of these been scarce consequently detailed understanding processes responsible for experimental phenomena are often lacking despite huge interest materials. Even more importantly, there a limited number structure-property studies different material compositions, research is generally by trial error rather than design. Here we discuss issues identify questions which need be answered design with further improvements.
