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

Abstract

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 cm2 active area. In order to increase the FF for PSC, we introduce a metal mesh design for connecting TCO layers. With the metal mesh inside, the best power conversion efficiency (PCE) of 20.46% with 1.02cm2 was performed.
