Abstract

Double barrier Quantum Dot structures are potential candidates for Energy Selective Contacts for Hot Carrier Solar Cells. Silicon QD in SiO2 matrix is studied for its energy selectivity using a two dimensional model. The impact of the disorders-configurational, morphological, thickness variations of the SiO2 barriers- on conductance and selectivity of the structure is studied. Application of an external electric field modifies the confinement potential and thus the resonant properties of the structure. The impact of the applied electric field on the properties of the energy selective contact is also studied in this paper.
