Titanium dioxide (TiO2) electron transport layers (ETLs) are still widely used in perovskite solar cells (PSCs) due to their compatibility with existing printing technologies and favorable energy level alignment for efficient electron extraction. However, TiO2 ETLs suffer from surface defects, e.g....
