Micro-/nanoimprint lithography is a high-throughput, high-resolution, and low-cost mass production fabrication process often used for creating microfluidic devices and optical components. In the imprint lithography process, a surface pattern of a stamp is replicated into a material by mechanical contact and three dimensional material...

The ever increasing installed capacity of renewable, sustainable energy is essential in order to keep the earth
habitable. However, the intermittent nature of solar and wind energy do not strictly follow human energy
demands. Therefore an energy of sufficient magnitude buffer is essential to provide a constant supply of
energy that...

Solar cells are showing significant promise to become the solution for the growing energy needs of our world. However for this to happen, new disruptive technologies with high efficiency and low cost are needed in the market. One possibility comes from multijunction thin film solar cells based on a-Si alloys and nc-Si. For this purpose a–SiO master thesis 2017

Cellular stiffness plays an important role for several diseases such as atherosclerosis, malaria and cancer. Cellular stiffness can be derived by the velocity of a cell that is squeezed through a constriction channel. For example, a rigid cell will move slowly through the constriction channel and vice versa. In this research a microfluidic...

Martensitic and bainitic steels are two types of widely used steels with excellent mechanical behaviors in automatic industry. It’s universally acknowledged that as- quenched martensite possesses poor ductility and impact toughness, which should be tempered before putting into application. During tempering, as-quenched martensite changes from a...

To improve the performance of the high efficiency c-Si solar cells within the PVMD group several front metallization methods were investigated. The objective was to decrease the series resistance, which would lead to an increase in FF and thus efficiency. Three different cell structure are examined; i) a poly-poly cell with SiN¬x as an ARC, ii)...

In the transition towards a renewable based energy supply, one of the main challenges is the intermittent nature of most renewable energy sources. In order to ensure a stable energy supply, different storage technologies attract a lot of research attention. For long term storage, using hydrogen as artificial fuel is a promising option. However,...

A tremendous amount of research in improving the efficiency of the single junction crystalline silicon (c-Si) based solar cells has brought its efficiency (26.6%) close to the theoretical maximum achievable conversion
efficiency (29.43%) [1–3]. Thus to further improve the efficiency, new avenues of reducing losses need to be opened up. One...

PowerWindow is a luminescent solar concentrator which employs a Tm2+-doped material to strongly absorb sunlight and produce a sharp emission in the near-infrared spectrum for energy-harvesting purposes. The absence of self-absorption and the large spectral overlap with the solar spectrum make it an attractive addition to current building...

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 ...

Crystalline silicon (c-Si) solar cells based on the polycrystalline silicon (poly-Si) passivating contact is becoming one of the most promising solar cell structures that enable high efficiency due to the minimization of metal contact recombination. The interdigitated back contact (IBC) crystalline silicon (c-Si) solar cells based on poly-Si...

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...

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...

With electron beam lithography, a cutting edge technology has been developed that might introduce new possibilities in the design of chips. The word "might" has been used here because e-beam lithography is not yet available for the mass production market. One of the bottlenecks in the development of e-beam lithography is the positioning...
