摘要	High-density and vertically-aligned cadmium sulfide quantum dots (CdS QDs) sensitized Zinc oxide nanorods (ZNRs) heterostructure as photoelectrode had been used to fabricate the quantum dots sensitized solar cells. The effect of post-annealing temperature was investigated on their photovoltaic performance. The power conversion efficiency was improved significantly after annealing treatment, which can be attributed to two factors: on the one hand, the increase in grain size of CdS quantum dots after annealing results in the enhancement of absorption intensity and expansion of absorption spectral range; on the other hand, the post annealing treatment can reduce the defect concentration and highly improve the crystallization quality of the ZNRs/CdS photoelectrodes. The highest power conversion efficiency of the solar cell can achieve 1.14% with a JSC of 5.27 mA/cm2 and a VOC of 0.51 V under the white light illumination intensity of 100 mW/cm2. 2013 Elsevier B.V.
