Deposition of silicon nanostructures by thermal chemical vapour deposition
(University of the Western Cape, 2015)In this thesis we report on the deposition of silicon nanostructures using a 3-zone thermal chemical vapour deposition process at atmospheric pressure. Nickel and gold thin films, deposited by DC sputtering on crystalline ... -
Silicon nanowires by metal-assisted chemical etching and its incorporation into hybrid solar cells
(University of Western Cape, 2021)The rapid increase in global energy demand in recent decades coupled with the adverse environmental impact of conventional fuels has led to a high demand for alternative energy sources that are sustainable and efficient. ... -
Tin Catalyst preparation for Silicon Nanowire synthesis
(University of the Western Cape, 2018)Solar cells offer SA an additional energy source. While Si cells are abundantly available they are not at an optimal efficiency and the cost is still high. One technology that can enhance their performance is SiNW. ... -
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 ...
