Congratulations Bin and Siraj on their new publication “Light-activated interlayer contraction in two-dimensional perovskites for high-efficiency solar cells”

Bin and Siraj along with our collaborators Dr. Jacky Even, Dr. Mercouri G. Kanatzidis, Dr. Jean-Christophe Blancon report that continuous light illumination leads to >1% contraction in the out-of-plane direction in two-dimensional hybrid perovskites, which is reversible and strongly dependent on the specific superlattice packing.   The onset of the light-induced contraction is synchronized to…
