Abstract

TiO2 nanoflower (NF)-ZnO composite films were synthesized by using liquid phase deposition (LPD) and dip coating method. At the lower growth temperature below 50 °C, the morphology of the sample is nanoflower, while at the temperature above 50 °C, the morphological shape of nanoparticle was obtained. The diameter of ZnO nanoparticle decreases 21.0% with the growth temperature. The thickness of the sample increases with growth temperature until the optimum temperature of 50 °C. The absorption of the uncoated dye samples is about the same. The decrease percentage of absorption for the coated dye samples is 15.0%. The dye-sensitized solar cell utilizing the TiO2-ZnO composite synthesized at 30 °C demonstrated the highest photovoltaic performance with η = 0.63 ± 0.02%, Jsc = 1.91 ± 0.05 mA cm−2, and Voc = 0.64 ± 0.02 V due to the highest optical absorption, lowest leak current, highest dye loading, smallest bulk resistance (Rs), highest recombination resistance (Rcr), and longest charge carrier lifetime (τ).
