Witryna18 sie 2024 · As the crystallization of FAPbI 3 is sensitive to the annealing temperature, such temperature gradient might manipulate the FA perovskite of crystallizing into the δ phase with low formation energy in the initial annealing stage, leading to an inevitable δ - α -phase transformation and deterioration of the quality of the final perovskite films [ … Witryna15 lut 2024 · However, these methods will enlarge the bandgap of FA-based perovskite and reduce the PCE. Besides phase stability, the crystallinity and oriented grain growth of perovskite film also has a dominating effect on the stability of devices. Oriented grain morphology can reduce the lattice strain and inhibit the migration of iodide. [26]
