Large Area (>1cm2) Efficient Perovskite/N type C-Si Tandem Solar Cell

In this article, we demonstrate mechanically stacked four-terminal perovskite-silicon tandem solar cells. N-type C-Si solar cell with PERT structure were used as the bottom cell and the perovskite solar cell on FTO glass substrate was used for top cell under 1.02 cm
