原始语种摘要: Abstract(#br)Nanostructured titanium dioxide thin films (TiO 2 ) have been deposited on indium tin oxide (ITO) substrate, using dip-coating process from partial hydrolysis and condensation of tetrabutylorthotitanate, and using butanol and acetic acid respectively as solvent and catalyst. The effect of film thickness on the microstructural, morphological and optical properties was investigated, as well as their applicability as electron transporting layer for planar perovskite solar cells (PSCs). In all cases, well-crystallized anatase TiO 2 films with a relatively smooth and homogeneous surface were obtained, while the optical band-gap of the films showed a small increase from 3.25 eV to 3.4 eV by increasing the film thickness from 50 nm to 90 nm. On the other hand, the refractive index...
