Researchers from China's Soochow University and other scientists have developed innovative approaches to improve the efficiency and stability of perovskite solar cells. One team created a dual-molecule interface layer that enhances charge extraction and stability, achieving a power conversion efficiency of 27.3%. Another group modified perovskite solar cells with CzOTf, resulting in cells with an efficiency of 26.20% and excellent stability. The scaled-up cells maintained a power conversion efficiency of 21.54% and operated outdoors for 35 days without degradation. These advancements in solar cell technology offer promising solutions for increasing renewable energy production.
