Disentangling star formation and AGN activity in the GAMA (G23) region
(University of the Western Cape, 2021)
Observations of galaxies at di↵erent wavelengths have shaped our understanding of their
formation and evolution through time. The commonly derived parameters, such as stellar
mass and star formation rate (SFR), rely on ...
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 ...
New Collective structures in the Z=76 stable odd neutron nucleus, 187Os
(University of the Western Cape, 2021)
Low- and medium-spin bands of 187Os have been studied using the AFRODITE array, following the 186W(4He,3n)187Os reaction at a beam energy of 37 MeV. The measurements of γ − γ coincidences, angular distribution ratios (RAD), ...
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 ...
Nial and steel as matrices and tic and oxynitrides as reinforcements in metal-matrix composite fabrication
(University of Western Cape, 2021)
Metal matrix composites harness the superior attributes of their individual constituents to form high performance materials that would rather be impossible from monolithic substances. Owing to many possible combinations, ...
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 ...
Hybrid lead halide perovskite thin films and solar cells by chemical vapour deposition
(University of the Western Cape, 2021)
The organic-inorganic hybrid perovskites such as methyl ammonium lead iodide (MAPbI3) or mixed halide MAPbI3-xClx (x is usually very small) have emerged as an interesting class of semiconductor materials for their application ...
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 ...
