In perovskite solar cells (PSCs), the most commonly used electron transport layers (ETLs) are titanium dioxide (TiO 2) and tin oxide (SnO 2).The problem with SnO 2 is that its conduction band does not match that of perovskites, while TiO 2 ''s photocatalytic nature can destroy perovskite materials.
