NUS scientists created a triple-junction perovskite/Si tandem solar cell with a 27.1% efficiency record.

Scientists at National University of Singapore (NUS) have created a novel triple-junction perovskite/Si tandem solar cell with a certified world-record power conversion efficiency of 27.1%. This advancement was achieved by engineering a stable and energy-efficient cyanate-integrated perovskite solar cell. The triple-junction solar cell can increase efficiency by stacking multiple layers of different photovoltaic materials, each absorbing solar energy within a different range. Current multi-junction solar cell technologies face issues like energy loss and instability during operation, but the NUS team's invention addresses these challenges.
