The record-breaking tandem cell fabricated using roll-to-roll manufacturing.

The Berlin team's cell combines a perovskite top layer with a conventional silicon bottom layer. The new cell reaches 47.6% efficiency — a gain achieved through a redesigned perovskite composition that reduces non-radiative recombination losses by 63%.
