Quantum-kinetic theory of steady-state photocurrent generation in thin films: Coherent versus incoherent coupling
U. Aeberhard
The generation of photocurrents due to coupling of electrons to both classical and quantized electromagnetic fields in thin semiconductor films is described within the framework of…
Nonequilibrium Green's function theory of coherent excitonic effects in the photocurrent response of semiconductor nanostructures
U. Aeberhard
Excitonic contributions to absorption and photocurrent generation in semiconductor nanostructures are described theoretically and simulated numerically using steady-state non-equil…
Quantum-kinetic theory of photocurrent generation via direct and phonon-mediated optical transitions
U. Aeberhard
A quantum-kinetic theory of direct and phonon mediated indirect optical transitions is developed within the framework of the non-equilibrium Green's function formalism. After valid…
Microscopic theory of absorption and emission in nanostructured solar cells: Beyond the generalized Planck formula
U. Aeberhard, U. Rau
Absorption and emission in inorganic bipolar solar cells based on low dimensional structures exhibiting the effects of quantum confinement is investigated in the framework of a com…
Spectral properties of photogenerated carriers in quantum well solar cells
U. Aeberhard
The use of low-dimensional structures such as quantum wells, wires or dots in the absorbing regions of solar cells strongly affects the spectral response of the latter, the spectra…
Microscopic non-equilibrium theory of quantum well solar cells
U. Aeberhard, R. H. Morf
We present a microscopic theory of bipolar quantum well structures in the photovoltaic regime, based on the non-equilibrium Green's function formalism for a multi band tight bindin…
