Toward cadmium-free spectral down-shifting converters for photovoltaic applications
Abstract(#br)Spectrum down-shifting converters based on Cd-free Zn–Cu–In–S(ZCIS)/ZnS core/shell quantum dots are modeled and simulated for applications in photovoltaics using the Monte-Carlo approach. The set of physical characteristics required for the successful implementation of this type of material in spectral converters have been identified. The advantage of using ZCIS/ZnS quantum dots in such converters is highlighted through a comparison with the conventional CdSe/ZnS quantum dots.
