Methods
Substrate preparation
Fluorine-doped tin oxide (FTO) glass substrates (Nippon Sheet Glass (NSG) 10 ?/sq) were
first patterned by chemical etching using Zn powder and 4M HCl solution. The etched
substrates were then thoroughly cleaned by ultrasonication in Hellmanex (2% in deionized
water) solution for 30 min, followed by sequential rinsing with de-ionized water, ethanol, and
acetone. The substrates were treated with UVó for 15 min to remove the last traces of
organic residues. A ?30 nm-thick blocking layer of TiO2 was subsequently deposited on FTO
via aerosol spray pyrolysis at 450 àfrom a precursor solution of titanium diisopropoxide
bis(acetylacetonate) (75% in 2-propanol) diluted in ethanol (1 : 9, volume ratio) with oxygen
as a carrier gas with sintering at 450àfor 30 min. The mesoporous TiO2 layer was deposited
by spin coating TiO2 paste of (Dyesol 30 NR-D) diluted in anhydrous ethanol (1:6 weight
ratio) at 4000 rpm for 20 s and consequently sintering of the substrates at 450àfor 30 min
under dry air flow. The as-prepared mesoporous substrates were transferred into a dry air
glove box after cooling down to 150 àfor perovskite deposition.
