Abstract

In this paper, an optoelectronic device simulation framework valid for arbitrary spatial variation of electronic potentials and optical modes, and for transport regimes ranging from ballistic to di usive, is used to study non- local photon absorption, photocurrent generation and carrier extraction in ultra-thin lm and nanostructure- based solar cell devices at the radiative limit. Among the e ects that are revealed by the microscopic approach and which are inaccessible to macroscopic models is the impact of structure, doping or bias induced nanoscale potential variations on the local photogeneration rate and the photocarrier transport regime.
