Harmonizing A‑Site Cation Incorporation With Conductive Grain‑Boundary Bridging for Durable Perovskite Solar Cells

ABSTRACT While perovskite solar cells (PSCs) have achieved significant progress in power conversion efficiency ( PCE ), their commercialization remains hindered by a critical challenge: irreversible efficiency degradation during device operation, primarily caused by the spontaneo...
