Scientists at the National University of Singapore (NUS) have demonstrated a perovskite–organic tandem solar cell with a certified world-record power conversion efficiency of 26.4% over a 1 cm2 active area—making it the highest-performing device of its kind to date. This milestone is driven by a newly designed narrow-bandgap organic absorber that significantly enhances near-infrared (NIR) photon harvesting, a long-standing bottleneck in thin-film tandem solar cells.
