Formamidinium Bromide Applications

• Perovskite Solar Cells:

Perovskites based on FAI provide enhanced efficiency and long-term stability of solar cell performance.

• Photovoltaics:

FAI is a preferred choice in tandem solar cells and in hybrid halide perovskite compositions that may contain mixed cations (formamidinium, methylammonium) to optimize efficiency and durability.

• Optoelectronics:

In addition to solar cells, FAI is also investigated for use in other optoelectronic devices such as light-emitting diodes (LEDs) and photodetectors.

FAQs

Q1: How is Formamidinium Bromide used in solar cells?

Answer: FABr is combined with lead bromide (PbBr₂) to form perovskite materials such as formamidinium lead bromide (FAPbBr₃). These perovskites exhibit a higher bandgap compared to iodide-based perovskites, making them suitable for use in tandem solar cells that capture various parts of the solar spectrum.

Q2: What makes Formamidinium Bromide better than other halides such as Methylammonium Bromide?

Answer: FABr forms more stable perovskite structures compared to methylammonium bromide (MABr). Perovskites based on FABr are thermally stable and moisture-resistant, resulting in a longer lifespan of devices and better performance under real-world conditions.

Q3: What is the bandgap of perovskites based on Formamidinium Bromide, and why is it important?

Answer: Perovskites based on FABr, such as FAPbBr₃, have a bandgap of approximately 2.3 eV. This higher bandgap makes them ideal for applications requiring selective light absorption or emission, such as in tandem solar cells, where different materials absorb different wavelengths of sunlight to improve overall efficiency.
