Abstract: Metal halide perovskites are revolutionizing solar technologies with their remarkable properties, propelling solar cells nearing the theoretical efficiency cap. To break through this barrier, tandem solar cells are conceptualized, in which different materials are stacked to better utilize the solar spectrum. Despite their rapid evolution, perovskite-based tandem solar cells encounter challenges with efficiency and stability, in which halide phase segregation plays a great role. In our work, we point out that photoinduced iodine escape is the trigger for segregation and design an organic additive accordingly, which mitigates iodine escape and phase segregation. The wide-bandgap perovskites therefore present enhanced performance. When paired with an organic subcell, we realize perovskite-organic tandems with a record-high efficiency. We believe that insights gained on halide phase segregation and optimized tandem performance will pave the way for subsequent research and commercialization.
