【Abstract】 Zinc oxide-coated tin oxide（SnO₂/ZnO）powder was prepared by a facile method.The SnO₂/ZnO composite powder was characterized by X-ray diffractometer.SnO₂/ZnO composite porous films utilized in dyesensitized solar cells（DSSCs）were prepared using one-step electrophoretic deposition（EPD）method.The asdeposited films showed no cracks when the film thickness was 33μm.The amount of ZnO coating and film thickness are optimized to achieve high energy conversion efficiency.The SnO₂/ZnO composite films deposited on flexible conducting substrate were extruded by apresser.The effect of ZnCl2 contents on photoanode properties of SnO₂/ZnO composite films was investigated.The results of SEM show that the SnO₂/ZnO composite films became smoother and the nanoparticles in the films became closer to each other.The photoelectrical properties of the SnO₂/ZnO composite films electrodes were significantly enhanced by this post-treatment.The open circuit voltage and short circuit current density were both increased.The optimized SnO₂/ZnO composite films photoanodes based on ITO/PEN substrate showed an overall power conversion efficiency of 3.95% under AM1.5 Gillumination（100 mW/cm2）,having a short circuit current density,open circuit voltage,and fill factor of16.43 mA/cm2,0.493 Vand 0.49,respectively.更多还原
