Cyanate-Integrated Solar Cells Achieve Record Efficiency

• Revolutionizing solar technology: Researchers achieve record efficiency of 27.1% with cyanate-integrated perovskite solar cells. Stability and energy efficiency improved.

Researchers at NUS, Beijing University of Technology, Suzhou Maxwell Technologies, and Technical University of Munich have developed a triple-junction perovskite/Si tandem solar cell with a record efficiency of 27.1%. This was achieved by integrating cyanate into the perovskite structure, improving stability and energy efficiency. The team, led by Asst Prof Hou Yi, demonstrated the successful use of cyanate to boost power conversion efficiency and stability in perovskite solar cells.

The new perovskite solar cell with cyanate integration showed higher voltage and reduced energy loss compared to conventional cells. After continuous operation for 300 hours, the solar cell remained stable and functioned above 96% capacity. The team also assembled a triple-junction perovskite/Si tandem solar cell, which achieved a certified efficiency of 27.1%, setting a new course for the development of perovskite-based solar technology.
