Welcome
to my website dedicated to the quantum theory of photovoltaic device operation. It features my research concerned with the
development of the theoretical description and numerical simulation of novel
nanostructure based solar cell devices. The main approach relies on
quantum-kinetic theories such as NEGF to cover the relevant physical
processes of the photovoltaic device operation under full consideration
of quantum effects present at the nanoscale. In this way,
photogeneration, photocarrier transport and recombination can be
treated on equal footing for arbitrary combinations of low-dimensional
absorber and conductor components. Applications include, e.g., ultrathin absorber devices, III-V
quantum well solar cells, silicon
based quantum well and quantum dot superlattice solar cells, novel
tunnel junction architectures for multijunction solar cells and quantum
dot fluorescence for spectral concentration devices. More about the
research can be found
