New Insight for Stabilizing Halide Perovskite via Thiocyanate Substitution

α-FAPbI3, a promising solar cell material with a cubic perovskite structure that is metastable at room temperature, can be stabilized by introducing a pseudo-halide ion like thiocyanate (SCN–) into its structure, demonstrated by Tokyo Tech researchers in a new study. Their finding provides new insights into the stabilization of the α-phase via grain boundary and pseudo-halide engineering.
