How does energy filtering improve quantum-dot based photovoltaic devices

Abstract : We investigate how energy filtering manifests and operates inside a quantum dot-based photovoltaic device by means of the Green’s function formalism. We find that the filtering process increases both charge and heat currents produced in the device. However, currents surprisingly show minima when the filter energy is equal to the absorbing dot energy due to a reduced carrier photogeneration at resonance.
