| Hazard Information | Back Directory | [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].
