In this study, we report on the low-temperature (<120 degrees C) fabrication of a mesoporous titanium dioxide (TiO2) layer for use in perovskite solar cells. The TiO2 layer used was produced from a solution of TiO2 nanoparticles, purified water and titanium isopropoxide (TTIP) acting as a precursor of an inorganic binder network. We compared the properties of TiO2 layers resulting from different molar ratios (ranging from 0.1:1 similar to 0.5:1) of titanium isopropoxide to TiO2 nanoparticles. Finally, perovskite solar cells were fabricated based on our optimized TiO2 molar ratio (TTIP:TiO2 = 0.1:1) and found to exhibit a short-circuit current density of similar to 16.01 mA cm(-2) and photoelectric conversion efficiency of similar to 5.57%, respectively.
