Improved Crystallization-Front Dynamics Reduce Buried-Interface Defects in Perovskite Solar Cells

Abstract Inverted perovskite solar cells have achieved substantial efficiency gains owing to advances in surface passivation; as a result, progress is now limited by buried defects at the perovskite/hole transport layer (HTL) interface. During top-down perovskite crystallization,...

Metformin Spacer Conformation Is a Structure-Directing Element in a 2D Perovskite with Strong X-ray Response

Abstract Direct X-ray detection in two-dimensional (2D) hybrid metal-halide perovskites is dictated by the interplay between organic spacer chemistry, crystal structure, and charge transport. Among these materials, the metformin (MF2+)-based perovskite MFPbI4 has recently emerged...
