Chinese scientists set world record in solar cell efficiency

(ECNS)— Chinese scientists have just developed perovskite-organic tandem solar cells with a record-breaking steady-state power conversion efficiency of 28.04%, marking a breakthrough for the nation’s solar energy research.

The study, published in the journal Nature on Monday, was conducted by a research team led by Li Yongfang and Meng Lei from the Institute of Chemistry under the Chinese Academy of Sciences.  

The record was achieved through a "full-stage regulation" strategy built around a photo-transformable additive molecule, marking a key step toward the practical application of perovskite-organic tandem solar cells.
