Vertically aligned silicon nanowires synthesised by metal assisted chemical etching for photovoltaic applications
(University of the Western Cape, 2015)
One-dimensional silicon nanowires (SiNWs) are promising building blocks for solar cells as they provide a controlled, vectorial transport route for photo-generated charge carriers in the device as well as providing ...
TiO₂ nanotube based dye-sensitised solar cells
(University of the Western Cape, 2012)
The first report of a functioning photo-electrochemical solar cell in 1991 attracted a lot of interest from scientists and industrial groups. From an industrial point of view these so-called dye-sensitised solar cells ...
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 ...
TiO2 nanotube based dye- sensitised solar cells
(University of Western Cape, 2012)
This work investigated the synthesis of Al2O3-coated TiO2 nanotubes via the anodisation technique for application in DSCs. TiO2 nanotube arrays with
an average length of 15 μm, diameter of 50 nm and wall thickness of 15 ...
Charge transfer efficiency and optical properties of P3HT/PCBM spin coated thin films
(UWC, 2009)
The efficiency of organic photovoltaics is influenced by the structure of the polymer, the morphology of the film, the interfaces between the layers, the choice of electron acceptor material and the ratio between the ...
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 ...
Nitrogen and argon treatment of titanium dioxide nanowire arrays
(University of 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 ...
Application of vertically aligned arrays of metal-oxide nanowires in heterojunction photovoltaics
(University of the Western Cape, 2020)
The commercial need to improve the performance of low-cost organic solar cells has led to the idea for this research. The study discusses the synthesis of one dimensional TiO2 and ZnO nanowire arrays synthesised using a ...
Metal assisted chemically etched silicon nanowires for application in a hybrid solar cell
(University of the Western Cape, 2018)
Photovoltaic (PV) devices based on inorganic-organic hybrid active layers have been
extensively studied for over a decade now. However, photoactive hybrid layers of
material combinations such as rr-P3HT and SiNWs still ...
Structural features of air-processible methyl ammonium lead triiodide (MAPbI3) perovskite thin films grown on Al-doped ZnO Nanowire Arrays
(University of the Western Cape, 2023)
The performance of air stable, mixed halide (MAPbI3-xClx) perovskite based solar cells is highly dependent on the quality and stability of the perovskite thin film, which in turn, is dependent on the substrate on which it ...
