Grain Boundary-Confined Lead Halides Mitigate Post-Treatment Surface Lattice Distortion in Wide-Bandgap Perovskites for Efficient Tandem Solar Cells

Abstract Wide-bandgap (WBG) perovskite solar cells (PSCs) have attracted increasing attention due to their essential role in high-efficiency tandem architectures. Post-treatment strategies are commonly employed to improve WBG perovskite films by modifying surface states and enhan...
