Due to the high-efficiency potential over 40%, the two-terminal (2T) perovskite/c-Si tandem solar cell becomes a desirable and promising candidate for solar cells. The photovoltaic materials and devices (PVMD) group in TU Delft has developed the c-Si solar cell using poly-SiOx as carrier-selective passivating contacts. The utilization of poly...

Quantum-limited parametric amplifiers have become increasingly interesting and relevant with the progressing field of quantum computing. However, currently it is still challenging to fabricate these complex devices. In this thesis, we developed cross type Josephson junctions (JJs), lumped element LC resonators, lumped element Josephson...

Multijunction devices based on thin film silicon are useful for a range of applications due to their low costs, better performance at higher temperatures, potential for flexibility, and light weight. One particularly interesting application of such devices is in solar-to-fuel conversion. In light of this, the goal of this thesis was to suggest...

For the continued growth of PV capacity, it will be necessary to store vast amounts of energy to overcome seasonal differences in energy generation. To this end, the conversion of electricity to liquid or gas fuels could play an important role in the future energy system. There are numerous ways to create fuels from solar energy, the...

The future of our energy supply cannot continue to depend on the use of exhaustible fossil fuels. The successful transition to a society powered by renewable energy sources is one of the major challenges our current generation faces. Renewable systems will only fully establish themselves if high conversion efficiencies can be obtained at a...

In this thesis, two new types of crystalline silicon texturization were developed, eventually aimed to be used in a triple junction solar cell from monocrystalline silicon and two thin film silicon alloy layers. The bottom of the two thin film silicon layers is made of hydrogenated nanocrystalline silicon (nc-Si:H). The current problem with this...

The edge states in finite quantum Hall graphene have previously been shown to be valley polarised for zigzag and armchair edges. Assuming that the valley isospin is also conserved at a smooth normal-superconducting (NS) interface, theoretical research has previously predicted that plateaus in the longitudinal conductance are expected to occur in...

Multi-junction solar cells with Si alloys have true potential for high conversion efficiency, because of the spectrum splitting capability. For optimal spectral utilization, a multi-junction silicon based device needs a silicon alloy with a bandgap between that of nc-Si (1.1 eV) and a-Si (1.8 eV). a-SiGe:H has a tunable bandgap between 1.4-1.6...

Current brain simulators do no scale linearly to realistic problem sizes (e.g. >100,000 neurons), which makes them impractical for researchers. The goal of the thesis is to explore the use of true multi-GPU acceleration on computationally challenging brain models and to assess the scalability of such models given sufficient access to multi...

A single photon interacting with a single atom is the most fundamental form of light interacting with matter and has been extensively studied in the field of Cavity Quantum Electrodynamics (cavity QED). Here, a non-linearity like an atom is coupled to a single mode of the electromagnetic field in a cavity. Another field which explores the...

In this thesis, contact resistivity for carrier-selective contacts (CSCs) is evaluated by using finite element simulations TCAD Sentaurus. First, the process of transmission line measurement (TLM) is modelled and validated based on current-voltage (I-V) data comparison between reference experiment and simulation results on polycrystalline...

In this thesis, a we have designed and fabricated a Josephson Parametric Amplifier (JPA) using a new double-angle evaporation method without a Dolan bridge. We have found and resolved several issues in the fabrication procedure, but it requires further tuning before being fully functional. We have also simulated the behaviour of a general...

In this thesis, the methods of Matrix Product States are examined. We give background in the origin of the methods and explain in detail how the method can be applied to a series of Josephson junctions. Numerical results are given for the ground state energy analysis of these series.

This thesis focuses on electronic transport modelling in molecular junctions. The most common technique for modelling electron transport is the combination of Density Functional Theory (DFT) and Non-Equilibrium Green's Function's (NEGF). Conventional DFT+NEGF methods are, however, invalid for correctly modelling junctions under a bias voltage. ...

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

Junction flow denotes the fluid phenomenon where the flow on a flat surface encounters a protuberance. This type of flow, which is highly three-dimensional, turbulent and unsteady, usually leads to the generation of a Horseshoe vortex at the obstacle's leading edge. Existing extensive experimental and numerical studies focus on the inception of...

The study of the dynamics of large, complex networks is generally very hard. Analytical solutions are rarely available and numerical solutions require immense computation times. Recently, Gao et al. [1]have proposed a new theoretical approach to analyse the average behaviour of complex networks. In this research we discuss the derivation of the...

The historic city centre of the Lithuanian capital of Vilnius is formed by an urban fabric consisting out of courtyards creating introvert voids within the traditional urban solid. These courtyards contrast the traditional and formal public spaces of the city by the way they operate on the levels of public-private accessibility, spatial...
