Wide‐bandgap (WBG) perovskites featuring 1.65–1.70 eV bandgaps are highly desirable light‐harvesting layers to construct high‐performance tandem photovoltaics. However, the complex multi‐component precursor system, especially the asymmetric nucleation of I‐rich and Br‐rich phases during film formation, often leads...

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...

In molecular complexes, ligand-to-metal charge transfer (LMCT) excited states enable efficient photoinduced charge separation and strong redox reactivity, but their operation is typically limited to short ultraviolet excitation. Extending LMCT absorption into the visible region utilizing strongly donating ligands often...
