On July 13, a groundbreaking study by the research team led by Li Yongfang and Meng Lei from the Institute of Chemistry at the Chinese Academy of Sciences was published in the esteemed international academic journal Nature. The team introduced a 'comprehensive-stage regulation' strategy, which involves the incorporation of photoswitchable additive molecules. This innovative approach enabled them to successfully fabricate high-performance perovskite-organic tandem solar cells, achieving a remarkable stabilized power conversion efficiency of 28.04%.

This milestone not only sets a new global benchmark for the power conversion efficiency of such devices but also represents a significant leap towards their practical utilization. These solar cells boast a unique combination of lightweight design, flexibility, and high specific power, positioning them as ideal candidates for diverse applications across various sectors. In the future, they hold immense potential for integration into construction, transportation, and wearable devices, offering versatile energy solutions. Moreover, they can significantly enhance energy security in the aerospace industry.
