Ge, H. (author)To improve the conversion efficiency of c-Si solar cells, it is crucial to quench the recombination losses at c-Si/metal interface. Such recombination losses are able to be reduced by using carrier-selective passivating contacts by means of hydrogenated amorphous silicon (a-Si:H) and poly-crystalline silicon (poly-Si)/tunneling silicon oxide ...master thesis 2017

van Doorene, S. (author)In the ongoing search for (new) highly efficient and cheap photovoltaic materials, orthorhombic barium disilicide has sparked recent interest. Studies have shown that BaSi2 exhibits good electrical properties, a bandgap of 1.3 eV and a high absorption coefficient. However, these studies have mainly been performed on molecular beam epitaxially...master thesis 2017

Phung, T.T.N. (author)To reduce the usage of Indium (rare material) in CIGS, ultra thin, high efficiency CIGS based solar devices have been developed in our group. One approach is to fabricate hybrid tandem cells between hydrogenated amorphous silicon and CIGS. Because the a-Si:H top sub-cell limits the current of such a device, it is desirable to texture the top...master thesis 2017

Prabu Harsarapama, A. (author)As the number of large scale photovoltaic power plants (which also known as solar parks) is growing in recent years, standard activities related to the system such as the operation and maintenance of the plant and grid management have become more crucial. In order to ensure a standard quality of these activities, accurate irradiance measurement...master thesis 2017

Vlasman, I. (author)As the state of the environment deteriorates due to the large energy consumption in the world, the importance of green technologies like photovoltaic (PV) generators and electric vehicles (EVs) increases. Both are making their appearance as common technologies in the modern life. However, separately these technologies can have bad influences on...master thesis 2017

Hofgärtner, A. (author)The building sector accounts for 30% of the total energy consumption worldwide, which has a large potential for improvement in energy demand (OECD/IEA, 2015). In the Netherlands a large part of the building stock are existing houses and that eventually need to be transformed to become energy neutral. The scale of the neighbourhood makes it...master thesis 2017

Mostert, E. (author)Electrical trains are fed with a high voltage to reduce transmission losses. In the train, these voltages have to be stepped down to a voltage that could be fed into the traction motors. This is done with IGBT based power converters. The use of IGBTs in power converters has some disadvantages: they generate a lot of heat and are therefore not...master thesis 2017

Feenstra, T. (author)One potential problem associated with the high electrical frequency in high-speed electrical machines are additional iron losses near the end-windings. They are expected to be a significant part of the total iron loss. The reader is introduced to currently known methods to study high-frequency iron loss estimation and end-effects in laminated...master thesis 2016

Pieper, J.T. (author)A meshed North Sea offshore electricity grid with high renewable energy penetration, as envisioned by the European Commission, is still at its infancy. Currently, point-to-point high-voltage DC interconnections across borders are already being implemented successfully, but the next steps of expanding these interconnectors with additional...master thesis 2016

Falkenberg, M. (author)Despite the fact that renewable energy sources are on the march, our energy system is still dominated by fossil fuels. In this energy transition storage is one of the main bottlenecks and attracts a lot of research. In order to compensate for the intermittent character of renewable sources like solar energy, the most developed options in the...master thesis 2016

Yeo, J.W.W. (author)Oil-filled terminations for high voltage XLPE insulated cables have been used for four decades in the Netherlands with a good service record. Prysmian would like to gain better insight into the effects of water contamination in insulating oil, to further extend the in-house experience and potential related failure mechanisms. High voltage...master thesis 2016

Tsakonas, P. (author)The recent developments in the offshore wind industry are pushing towards upgrading the inter-array voltage level from 33 kV to 66 kV. The main reason behind this, is the increased capacity of future wind turbines leading to an increased power density in the inter-array grid of the offshore wind farms. The current level of 33 kV cannot give cost...master thesis 2016

Zhang, M. (author)Power system blackouts have been observed increasingly frequent and severe. As an emergency control action to rescue the system from complete blackout, under-frequency load shedding (UFLS) technique can disconnect a part of the load when a disturbance occurs and an excessively low frequency is detected. Traditional UFLS scheme is widely adopted...master thesis 2016
