The metastable alpha phase of pure formamidinium lead halide perovskite has been obtained from controlled thermal growth. We have measured the activation energy of the heating rates able to kinetically activating the alpha phase. By using the flash infrared annealing method [1, 2], we have screened a large amount of sequential data. This data was compiled into a database to use as a reliable guide for fundamental studies of halide perovskites. Therefore, the correlation of thermal growth with morphology, structure, and photophysical behavior of the films under different growth conditions has been investigated. Thus, we manufactured highly stable perovskite solar cells with photonic sintering (antisolvent-free) for more than 500 hours.
