Quantum Photovoltaics Theory

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.
