Abstract

In this study, low cost and safe quantum dots sensitized solar cells QDSSCs were formulated. Two structures of alloy quantum dots (QDs) (i.e., core and core/shell) were investigated for titanium dioxide (TiO2) based QDSSCs. The synthesizing of CuInS (CIS) core QDs and CuInS/ZnS (CIS/ZnS) core/shell QDs were formulated via inorganic method. Using the core/shell structure CIS/ZnS for sensitizing TiO2 photoanode has a significant impact on the QDSSCs overall parameters such as open circuit voltage, short circuit current density and cell efficiency. This is because electrons injecting from the conduction band of the CIS/ZnS to that of TiO2 is easier than that from CIS to TiO2 nanoparticles and charge recombination reduction occurs at the interface between photoanode and electrolyte. The J-V curves suggest that the TiO2/ CIS/ZnS QDSSC exhibits the best photoelectric performance with Voc = 0.17 V, Jsc= 5.89 mAcm-2 and ɳ = 0.23% which are significantly higher than those of CIS/ TiO2 QDSSC.
