N -Shaped vs Λ-Shaped Bridging Symmetric Molecules: Geometric Compatibility Drives Performance Improvement in Perovskite Solar Cells

Abstract Intrinsic defects limit the further improvement of photovoltaic performance and stability of perovskite solar cells (PSCs). Bridging symmetric molecules have been proved to be a kind of promising additive for passivating defects within perovskites. However, there is curr...

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...
