Stabilizing Grain Boundaries by Flexible Bidirectional Multisite Hydrazide Cations toward High-Performance Inverted Perovskite Solar Cells

Abstract The grain boundary instability induced by defects and tensible strain impedes the realization of high-performance inverted perovskite solar cells (PSCs). Here, we propose a flexible bidirectional multisite additive strategy to stabilize perovskite. (6-(2,5-Dioxo-2,5-dihy...
