WebDimethylammonium iodide (DMAI) is the precursor for the DMAPbI3 2 H -perovskite structure. Unlike its MAPbI3 analogue, it is stable under ambient conditions for several months [1]. DMAPbI3 has a relatively large optical gap (Eg ∼ 2.59 eV), indicating the conductivity of such material is ionic, instead of being electronic.
