Simultaneous passivation of surface and bulk defects in all‐perovskite tandem solar cells using bifunctional lithium salts

Simultaneous passivation of surface and bulk defects in all‐perovskite tandem solar cells using bifunctional lithium salts

Abstract All‐perovskite tandem solar cells have garnered considerable attention because of their potential to outperform single‐junction cells. However, charge recombination losses within narrow‐bandgap (NBG) perovskite subcells hamper the advancement of this technology. Herein, we introduce a lithi...
