Perovskite films prepared with the help of these additives such as Benzylamine Hydroiodide exhibit better light harvesting performance and low charge recombination at the perovskite/TiO2 interface. Hybrid halide perovskites are emerging semiconducting materials, with a diverse set of remarkable optoelectronic properties. Besides the widely studied three-dimensional (3D) perovskites, two-dimensional (2D) perovskites show significant potential as photovoltaic (PV) active layers while exhibiting high moisture resistance.
