Inverted polymer solar cells using TiO2 film as electron transporting layer were fabricated with the structure of fluorine-doped tin oxide/TiO2 films/poly(3-hexylthiophene): [6,6]-pheyl-C-61-butyric acid methyl ester/Poly(3,4-ethylenedioxythiophene): poly(styrenesulfonate)/Ag. By tuning the crystalline structure of TiO2 films, the photovoltaic performance of the devices was remarkably enhanced. TiO2 was prepared by sol-gel method and their structures, morphologies and transmittance were characterized by X-ray diffraction, scanning electron microscope, and UV-visible spectrophotometer. Interestingly, for TiO2-3 film, which was prepared with tetrabutyl titanate, acetyl acetone and ethanol in a ratio of 1:0.5:6, the open-circuit voltage and fill factor of the device were up to 0.6 V and 64.8%, respectively, and the power conversion efficiency of TiO2-3 film was achieved up to 3.56% with the current density of 9.18 mA/cm(2) under an AM 1.5 G (100 mW/cm(2)) irradiation intensity. In the meanwhile, the stabilities of these devices were also studied and results showed that our work was better than the corresponding devices of conventional structure.
