In view of the continued controversy concerning the polar/nonpolar nature of the hybrid perovskite system, CH3NH3PbI3, we report the first investigation of a time-resolved pump-probe measurement of the second harmonic generation efficiency as well as using its more traditional form as a sensitive ...
Here we present compelling evidences that CH3NH3PbI3 crystals self-grown on FTO/TiO2 substrate consist of ferroic domains with alternating polar and nonpolar orders, in contrast to previous experimental and theoretical expectations, and polar domains possess reduced photocurrent. It is found that polar...

ΔGsolvation represents the solvation energy given by the sum of the polar contribution (ΔGPB/GB) and nonpolar contribution (ΔGSA). ΔGPB/GB can be obtained using the Poisson–Boltzmann or generalized-Born models, while ΔGSA can be calculated by solvent accessible surface area (SASA). ...
