Integrating Multifunctional Interfaces via Chelation-Driven Chemical Reconstruction Enables Efficient and Durable Perovskite Solar Cells
Interfacial instability is a critical constraint for the practical deployment of perovskite solar cells (PSCs), which commonly arises from the metastable residual PbI 2 and deep-level defects like under-coordinated Pb 2+ . Herein, a benzeneseleninic acid (PSA)-enabled interfacial chemical reconstruction strategy, tha...
