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.
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.

Application
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].
Uses
Organohalide based perovskites have emerged as an important class of material for solar cell applications. Our perovskites precursors are useful for synthesizing mixed cation or anion perovskites needed for the optimization of the band gap, carrier diffusion length and power conversion efficiency of perovskites based solar cells.
