n-Butylammonium bromide, high quality perovskite precursor

Used to tune perovskite nanoplatelet structures for perovskite LEDs and solar cells


Applications

N-Butylammonium bromide (BABr) is commonly used to tune colloidal perovskite nanoplatelet structures for desired absorption/emission energy and device performance for perovskite LEDs and Solar cells. [1]

When larger-group ammonium halides that act as surfactants (such as BAI or BABr) are added to the perovskite precursor solution, they dramatically constrain the growth of 3D perovskite grain. This results in the production of crystallites with dimensions as small as 10 nm, and a film roughness of less than 1 nm [2].
