Abstract
Double barrier Quantum Dot structures are potential candidates for Energy Selective Contacts for Hot Carrier Solar Cells. Silicon QDs in SiO2 matrix with SiC barriers make a very effective Energy Selective Contact and has several advantages over the same structure with SiO2 barriers. In this paper, the Energy Selective Contacts are studied for their energy selectivity using a two dimensional scattering matrix model. The improvement in conduction by using SiC barriers compared to that by using SiO2 barriers is studied quantitatively. The impacts of configurational and morphological disorders of the dots on the filtering properties of Energy Selective Contacts are analyzed. The impacts of external electric field and temperature on the electrical properties of the QD structure are also studied and the I-V characteristics is obtained.
