Two-sided solar panels break efficiency records

Summary

Researchers from KAUST and University of Toronto have created a two-sided perovskite/silicon tandem solar cell that exceeds the performance limits for tandem configurations. The bifacial design captures both direct sunlight and light reflected from the ground (albedo). Outdoor testing demonstrated efficiencies beyond commercial silicon solar panels. Why it matters: This innovation promises ultra-high power generation at affordable costs, potentially revolutionizing the photovoltaics market in the region and globally.
