Used in the fabrication of perovskite solar cells, where it acts as a precursor to form two-dimensional (2D) perovskite structures. The compound helps improve moisture stability and device efficiency by passivating surface defects in the perovskite layer. It is also employed in layered perovskite materials to tune bandgap and enhance optoelectronic properties. Additionally, it finds use in light-emitting diodes (LEDs) and photodetectors due to its favorable charge transport characteristics when incorporated into thin-film semiconductor layers.
