Lead-free hybrid perovskite N(CH3)4SnI3 with robust ferroelectricity induced by large and non-polar N(CH3)4 + molecular cation
The ferroelectricity in hybrid perovskite CH3NH3PbI3 is under debate. Here, the authors predict a Pb-free hybrid perovskite N(CH3)4SnI3 with non-polar molecular cation N(CH3)4+ showing strong ferroelectricity, good stability, and high visible-light absorption, ideal for high-efficiency solar cells.
