Tin-oxide thin films by thermal oxidation
(University of Western Cape, 2021)
Tin dioxide (SnO2) thin films are a worthy candidate for an electron transport layer (ETL) in
perovskite solar cells, due to its suitable energy level, high electron mobility of 240 cm2 v-1 s-
1, desirable band gap of ...
Construction and analysis of exponential time differencing methods for the robust simulation of ecological models
(University of Western Cape, 2021)
In this thesis, we consider some interesting mathematical models arising in
ecology. Our focus is on the exploration of robust numerical solvers which are
applicable to models arising in mathematical ecology. To begin ...
A study of the nearby interacting galaxy pair NGC 1512/1510
(University of Western Cape, 2020)
This work focuses on generating a new dynamical model of the nearby (9.5 Mpc) interacting
galaxy system NGC 1512/1510. Neutral hydrogen (H i ) observations from the Australia
Telescope Compact Array (ATCA) are used to ...
Computational modelling of a hot-wire chemical vapour deposition reactor chamber
(University of Western Cape, 2020)
In this thesis, I explore the subjects of fluid dynamics and the Hot-Wire Chemical Vapour
Deposition (HWCVD) process. HWCVD, in its simplicity, is one of the more powerful and
elegant deposition techniques available in ...
A study of neutron pairing correlations using the 136Ba(p, t) reaction
(University of Western Cape, 2020)
Observation of neutrinoless double beta decay (0 ) is currently the only
means by which one could establish the Majorana nature of neutrinos. Additionally,
such an observation would determine the absolute neutrino ...
Hydrogen storage capacity of the Ti-Pd multilayer systems
(University of the Western Cape, 2020)
Hydrogen has high energy density and it is regarded as the future energy carrier. Hydrogen can be stored as a gas in high-pressure cylinders, as a liquid in cryogenic tanks and as a solid in metal hydrides. The storage of ...
Effect of zinc oxide nanoridge height on solar cell performance
(University of Western Cape, 2021)
Environmentally friendly photovoltaic devices make use of solar radiation as the energy source to generate electricity. Organic solar cells (OSCs) have been making headway in the last decade due to their cost-effectiveness ...
An hi study of the nearby dwarf galaxy ic 4710
(University of Western Cape, 2021)
This work aims to study the dark matter content of the nearby (7.38 Mpc) dwarf
galaxy IC 4710 using the HI line observations from the Australia Telescope
Compact Array (ATCA). We produce the rst interferometric maps of ...
Optimization of lead halide perovskite thin films by chemical vapour deposition
(University of Western Cape, 2021)
Perovskite solar cells have gained tremendous attention within the past
decade, due to its rapid improvement in power conversion e ciency (PCE),
with the current record cell at 25%. The aim of this study is to create ...
Nitrogen and argon treatment of titanium dioxide nanowire arrays
(University of the Western Cape, 2021)
TiO2 nanoparticle films are important electron transport layers (ETLs) in photovoltaics such as
dye-sensitised, perovskite and polymer hetero-junction solar cells. These films, however, have
significant electron trap-sites ...
