In order to study on the photoelectric properties of nanocrystalline Z nO thin films which will serve as the anode material of dye-sensitised solar cell (DSSC),the fabrication of nano crystalline ZnO thin films and a series of measurements and characterizations were carried out in this paper.Firs tly,nanocrystalline ZnO films were fabricated on FTO-glass substrates by the sol-gel spin coating method and a ra pid thermal treatment.And the crystal phase and morphology were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM),respectively.Se condly,using ZnPc dye and PbS quantum dots (Q-PbS) as sensitizers,FTO/ZnO/ZnPc electrode,FTO/ZnO/Q-PbS electrode,and FTO/ZnO/Q-PbS/ZnPc electrode were prepared,respectively.And the UV-vis absor bance spectra of these electrodes were measured and analyzed.The results show that ZnPc dye and Q-P bS could well sensitize the ZnO nanoparticle film electrodes,among them,the sensitization effect of Q-PbS is better than that of ZnPc dye, and the effect of composite sensitization of ZnPc dye and Q-PbS is optimal.Fi nally,utilizing FTO/ZnO/Q-PbS/ZnPc electrode whose sensitization effect is optimal as photoele ctrode,a solar cell device was fabricated and its working characteristic curve (I-V cu rve was measured).In simula tions,a fill factor of 0.348,a schort-circuit photocurrent of 1.42mA,an open-circuit voltage of 304mV,and a overall light to electricity conversion efficiency of 0.696% are obtained.
