Abstract: The flexible ZnO-based dye-sensitized solar cells were prepared by chemical bath deposition method. The effect of kind and concentration of precipitants on ZnO film microstructure and DSSC photoelectric performance were studied. The phase composition and microstructure of the ZnO films were characterized by SEM and XRD, respectively. The photoelectric performance of DSSCs was tested by I-V testing system. The results show: the cell using the ZnO film prepared with 0.3 M HMT and 0. 1M Zn(NO₃)₂•6H₂O exhibited optimal performance under an AM-1.5 illumination. The Voc, Jsc, FF and PCE of the DSSC were 0.60 V, 2.57 mA•cm-2, 0.72 and 1.13%, respectively.
