Longi, Soochow University unveil 34.0% perovskite-silicon tandem solar cell based on dual-anchored interfacial design
Soochow University and Longi researchers developed a ZrO₂ interfacial strategy that reduces recombination and leakage while improving charge extraction in perovskite-silicon tandem solar cells. The resulting device achieved 2.014 V open-circuit voltage and retained 84% of its initial efficiency after 2,000 hours.
