[SMM PV Express] Over 28%! Perovskite-Organic Tandem Solar Cell Efficiency Breaks Record.

A research team from the Institute of Chemistry, Chinese Academy of Sciences (hereinafter referred to as ICCAS) has boosted the power conversion efficiency of perovskite-organic tandem solar cells to 28.04%, once again setting a new world record for such devices. The related research was published in *Nature* on July 13.

The corresponding author of the paper, Li Yongfang, an academician of the Chinese Academy of Sciences and a researcher at ICCAS, stated that perovskite-organic tandem solar cells combine the advantages of light weight, flexibility, and high specific power. They can be widely applied in ground-based scenarios such as buildings, transportation, and wearable electronic devices, and can also play a positive role in space fields including satellites, space stations, and deep-space exploration, serving as a vital energy guarantee for humanity’s march into space.

"This kind of cell is thin, lightweight, and portable; it can easily be placed in a backpack and carried around. During outdoor trips, you simply unfold it to charge electronic devices like mobile phones," Li Yongfang told *China Science Daily*.
