Understanding the Decoupled Effects of Cations and Anions Doping for High-Performance Perovskite Solar Cells
Highlights Alkaline earth cations are successfully incorporated into perovskite lattice with the aid of sulfonic acid anions, while alkaline earth metal halides are lack of doping capacity. The sulfonic acid anions effectively regulate the crystallization of perovskite and passivate the metallic Pb0...

| description | Highlights Alkaline earth cations are successfully incorporated into perovskite lattice with the aid of sulfonic acid anions, while alkaline earth metal halides are lack of doping capacity. The sulfonic acid anions effectively regulate the crystallization of perovskite and passivate the metallic Pb0 defect states, thereby improving the power conversion efficiency of perovskite solar cells. By comparing the property of FACF3SO3 and Ca(CF3SO3)2-doped perovskite films, the impact of suppressing halide migration with an activation energy of 1.246 eV is attributed to Ca2+ cations, thus providing methodology for decoupling the effects of cations and anions. |
