Techniques of TiO
2 film fabrication for dye-sensitized solar cells having a conversion efficiency of global air mass 1.5 (AM 1.5, 1000 W/m
2) solar light to electric power over 10% are reported. Newly implemented fabrication technologies consist of pre-treatment of the working photoelectrode by TiCl
4, variations in layer thickness of the transparent nanocrystalline-TiO
2 and applying a topcoat light-scattering layer as well as the adhesion of an anti-reflecting film to the electrode's surface. TiCl
4 treatments induce improvements in the adhesion and mechanical strength of the nanocrystalline TiO
2 layer. Optimization of the thickness of the TiO
2 layer, acting as the working electrode, affects both the photocurrent and the photovoltage of the devices. Covering of the TiO
2 photoanode by an anti-reflecting film results in enhancement of the photocurrent. Each of these components of film fabrication exerts a significant influence on the overall photovoltaic parameters of the devices resulting in improvements in the net energy conversion performance.
