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 p...
