Abstract

To investigate the photovoltaic properties of quantum dot connected to quantum wire reservoirs we rely on numerical calculations using the non-equilibrium Green function formalism. We examine impacts of the hopping parameter that controls the dot-wire contact for a monochromatic light resonant with the isolated dot gap. Global current and power increase when the hopping decreases, in particular the short-circuit current and the open-circuit voltage.
