In tandem solar cells made entirely of perovskite, the inverted structure employing organic charge transport carriers like PEDOT:PSS is therefore preferred. In a reaction of proportionation, metallic tin was employed to convert Sn 4+ to Sn 2+, yielding a PCE of 22.1 % in all tandem-based perovskite solar cells [63].
