Incorporation of γ-butyrolactone (GBL) dramatically lowers the phase transition temperature of formamidinium-based metal halide perovskites
Chemical Communications, 2019•pubs.rsc.org
We demonstrate that the δ to α phase transition temperature of formamidinium-based
perovskites is reduced by∼ 50° C through the incorporation of∼ 2 wt% γ-butyrolactone
(GBL) into the crystal lattice. The intercalation of GBL is found to expand the unit cell of the δ-
phase, reducing the energy barrier for thermal conversion.
