Nanoparticles and thin films for solar cells and light-matter interaction

This work involves nanoparticles for photovoltaics and light-matter interaction from a more fundamental point of view. I am using (plasmonic) metal and semiconductor (quantum dot) nanoparticles to enhance light trapping in thin film solar cells. For this research Atomic Force Microscopy, Luminescence, UV-Vis absorption spectroscopy, Transmission Electron Microscopy, XPS, UPS is used. Besides this research in novel concept photovoltaics we study the plasmonic behaviour of nanoparticles embedded in semiconductors with electron energy loss spectroscopy (EELS) and femto second laser spectroscopy. For this research we use a dedicated gas aggregation magnetron sputter cluster source to fabricate the nanoparticles. This is combined with a thin film magnetron sputter deposition system, with which almost any nanoparticle-thin film composite can be fabricated. Many of the advanced characterisation experiments are performed in international collaborations.
