  • Abstract
    We recently reported an NREL certified ~3% efficient device with structure of ITO/ZnO/PbS QD/Au. The device is remarkably stable in air without encapsulation for more than 1000 hours. Therefore, in this study we focus on devices with structure of ITO/ZnO/PbS QD/metal fabricated in air. By annealing PbS QD film at low temperature up to 140C, the solar cell efficiency can be achieved to more than 4%.
