Abstract

A monolithic (FAPbI3)0.83(MAPbBr3)0.17 perovskite/rear-textured-homo-junction-silicon tandem solar cell with a steady-state 21.8% efficiency has been achieved on 16 cm2 using a new front top metal grid design producing an impressive fill factor (76% under forward scan or 78% under reverse scan). The efficiency and fill factor are the highest for monolithic perovskite/Si tandems larger than 10 cm2.
