Tert-butylammonium iodide, (tBAI) is used as a perovskite precursor to enable 2D structures with smoother films achieve higher PCEs for perovskite LEDs and solar cells.
Due to its bulky group, Tert-butylammonium iodide is an ideal candidate to make perovskite structures less sensitive to moisture in the air, resulting in improved device stability and lifetime.
