The fate and transport of carbon-based nanomaterials in the environment
(University of Western Cape, 2020)
The interest in carbon-based nanomaterials, such as carbon-nanodots and graphene, has grown exponentially because these materials have unique properties and applications in the medical, electronic, clean energy and several ...
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 ...
