In a groundbreaking development, an international team led by scientists from the Institute of Chemistry under the Chinese Academy of Sciences has unveiled a novel high-efficiency solar cell.
Known as the perovskite-organic tandem solar cell, this innovative technology has achieved a photoelectric conversion efficiency of 26.4%, setting a new benchmark for such solar cells, according to Li Yongfang, an academician and researcher at the institute.
Perovskite and organic solar cells are heralded as the next generation of photovoltaic technology. Unlike the commonly used crystalline silicon solar cells, they offer significant advantages, including easier preparation, lighter weight, and the potential for flexible applications.
These attributes open up exciting possibilities for diverse applications such as portable energy solutions, building-integrated photovoltaics, and indoor solar technologies.
The novel solar cell operates by utilizing wide-bandgap perovskite materials to absorb short-wavelength sunlight, while the narrow-bandgap organic active layer captures near-infrared long-wavelength sunlight. This strategic combination effectively expands the usable solar spectrum, thereby enhancing the overall energy conversion efficiency of the device.
Li Yongfang emphasized that this advancement not only boosts efficiency but also paves the way for more versatile and sustainable energy solutions. The study detailing this breakthrough was recently published in the prestigious journal Nature.
