An international team led by scientists from the Institute of Chemistry under the Chinese Academy of Sciences has developed a new type of high-efficiency solar cell, marking a significant breakthrough in renewable energy technology.
The innovative perovskite-organic tandem solar cell achieves a photoelectric conversion efficiency of 26.4 percent—the highest efficiency recorded for this type of solar cell to date. According to Li Yongfang, an academician and researcher at the institute, this advancement opens new horizons for next-generation solar cells.
Perovskite and organic solar cells are emerging technologies that offer advantages over traditional crystalline silicon solar cells, including ease of fabrication, lightweight properties, and flexibility. These attributes make them ideal for applications in portable energy solutions, building-integrated photovoltaics, and indoor energy harvesting.
“Our novel solar cell leverages wide-bandgap perovskite materials to absorb short-wavelength sunlight, while a narrow-bandgap organic active layer captures near-infrared long-wavelength sunlight,” explained Li. “This combination significantly expands the usable solar spectrum and effectively enhances the device’s energy conversion efficiency.”
The team’s study has been published in the journal Nature, highlighting the global interest in advancing solar technology to meet increasing energy demands sustainably.
