Our partners at EMPA  have developed perovskite-perovskite tandem solar cells, stacking layers with different band gaps to capture a broader solar spectrum and achieve efficiencies up to 45%. Perovskite’s tunable band gap surpasses traditional silicon cells in performance, making it a revolutionary alternative for solar energy.

EMPA’s environmentally friendly and cost-effective perovskite production reduces manufacturing carbon footprints. This innovation enables integration into various applications like car roofs and buildings, enhancing solar energy efficiency and affordability for the future.
