Intermediate‐Phase‐Mediated Homogeneous Crystallization of Wide‐Bandgap Perovskite for Efficient Silicon/Perovskite Tandem Solar Cells

ABSTRACT Achieving compositionally homogeneous mixed‐halide (I − and Br − ) wide‐bandgap (WBG) perovskite films is crucial for high‐performance perovskite/crystalline silicon tandem solar cells (TSCs), yet the disparate crystallization kinetics of iodide‐ and bromide‐rich phases...
