Abstract

CdS quantum dots sensitized solar cells (QDSCs) based on screen-printed TiO2 nanoporous electrodes were assembled. The TiO2 nanoporous films were prepared by screen-printing technique which the thickness of TiO2 film was controlled through the screen printing cycles. The CdS quantum dots (QDs) were grown by the successive ionic layer adsorption and reaction deposition method. The efficiencies of the CdS-sensitized TiO2 solar cells were increased with the increasing the screen printing cycles. The assembled CdS QDSCs yield a best power conversion efficiency of 1.34% and a short-circuit current of 3.1 mA/cm2 with carbon counter electrode..
