1. By Means of Beams : Laser Patterning and Stability in CIGS Thin Film Photovoltaics
Abstract : Solar irradiation is a vast and plentiful source of energy. The use of photovoltaic (PV) devices to convert solar energy directly to electrical energy is an elegant way of sustainable power generation which can be distributed or in large PV plants based on the need. READ MORE

2. Sputtering-based processes for thin film chalcogenide solar cells on steel substrates
Abstract : Thin film chalcogenide solar cells are promising photovoltaic technologies. Cu(In,Ga)Se2 (CIGS)-based devices are already produced at industrial scale and record laboratory efficiency surpasses 22 %. Cu2ZnSn(S,Se)4 (CZTS) is an alternative material that is based on earth-abundant elements. READ MORE

4. Reactive sputtering and composition measurements of precursors for Cu2ZnSnS4 thin film solar cells
Abstract : Cu2ZnSnS4 (CZTS) is a thin film solar cell material that only contains abundant elements and for which promising conversion efficiencies of 9.2 % have been shown. In this thesis composition measurements and reactive sputtering of precursors for CZTS films have been studied. These precursors can be annealed to create high quality CZTS films. READ MORE

5. Probing the effects of photodegradation of acceptor materials in polymer solar cells: bulk, surface, and molecular level
Abstract : Polymer solar cells (PSC) have reached record power conversion efficiencies of over 15%. The operational lifetime of PSCs, however, has to increase for their use in large area outdoor applications. READ MORE
