Abstract:The passivation of the defects derived from rapid‐crystallization with electron‐donating molecules is always a prerequisite to obtain desirable perovskite films for efficient and stable solar cells, thus, the in‐depth understanding on the correlations between molecular structure and passivation capacity is of great importance for screening passivators. Here, we introduce the double‐ended amide molecule into perovskite precursor solution to modulate crystallization process and passivate defects. By regulating t… Show more
