Application

Formamidinium iodide (FAI) is an organic halide, which can be used as a precursor solution in the fabrication of perovskite-based heterojunction solar cells.
Formamidinium iodide (FAI) serves as a critical precursor material in the fabrication of perovskite solar cells. FAI is used in material engineering studies to investigate the impact of formamidinium incorporation on perovskite film properties and device performance.
The iodide and bromide based alkylated halides find applications as precursors for fabrication of perovskites for photovoltaic applications.

Photodetectors based on three dimensional organic-inorganic lead halide perovskites have recently received significant attention. As a new type of light-harvesting materials, formamidinium lead iodide (FAPbI3) is known to possess excellent optoelectronic properties even exceeding those of methylammonium lead iodide (MAPbI3).

Solar Cells: Towards Printable and Flexible Solar Technologies

To achieve net-zero emissions by 2050, renewable power contributions must triple. Photovoltaic stations provide vital utility power, achieved primarily through third- and fourth-generation technology. Promising trends include recycling and revolutionary, ultra-lightweight, flexible, and printable solar cells.
