Formamidinium Lead Iodide Usage And Synthesis

Uses

Formamidinium lead iodide salts have the characteristics of high carrier mobility, long diffusion length, wide light absorption range, and band gap size suitable for the solar spectrum, and are widely used in the field of high-efficiency photovoltaic cells.

Description

Currently, the high-efficiency perovskite solar cells are predominantly fabricated with formamidinium lead iodide (FAPbI3), which exhibits higher thermal stability against decomposition into the secondary compound of PbI2, a broader absorption spectrum that extends further into the red, and an ideal bandgap (~1.4?eV) closer to the Shockley–Queisser optimum, as compared with the prototypical methylammonium lead iodide (MAPbI3). The superior optoelectronic properties of FAPbI3 originate from the high-symmetry cubic perovskite structure (black α-phase). At room temperature, the black phase, also known as α- phase, of FAPbI3, evolves towards the most stable non-perovskite hexagonal yellow δ-phase (δ-FAPbI3) because α-FAPbI3 is thermodynamically unstable at temperatures below 150 °C[1].

Advantages

Formamidinium Lead Iodide has the advantages for: High efficiency:The conversion efficiency of Formamidinium Lead Iodide has reached a high level of more than 25% in the laboratory; Broad spectrum absorption: It can fully absorb the radiant energy of solar energy; High stability:It has good stability and long service life; Environmental protection: It contains relatively rich, extensive, accessible and environmentally friendly elements,.
