New high-efficiency solar cell created by Chinese promises to change the future of clean energy
An international team led by scientists from the Institute of Chemistry of the Chinese Academy of Sciences has developed a new type of high-efficiency solar cell.

The perovskite-organic tandem solar cell can achieve a photoelectric conversion of 26.4%, the highest efficiency for such solar cells to date, according to Li Yongfang, an academician and researcher at the institute.
Perovskite solar cells and organic solar cells represent the next generation of solar cells. Compared to currently widely used crystalline silicon solar cells, they offer advantages such as ease of manufacturing, light weight and the ability to be applied in flexible devices.
These features present significant application prospects in areas such as portable power, building-integrated photovoltaics, and indoor photovoltaics.
The new cell uses broadband perovskite materials to absorb short-wavelength sunlight and the narrow-band organic active layer to absorb long-wavelength sunlight in the near-infrared, Li said.
He added that this combination significantly expands the usable solar spectrum and effectively increases the device's power conversion efficiency.
