Intermediate-Phase-Mediated Homogeneous Crystallization of Wide-Bandgap Perovskite for Efficient Silicon/Perovskite Tandem Solar Cells.
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 readily induce halide segregation and inhomogeneous...
