Determination of effects of reverse bias on the efficiency of dye solar cells with the aid of spectroscopic and impedance studies

Author: Le Roux, Lukas J Date: Sep 2010 The work that is presented here is focused on the results that were obtained during studies of the performance of the DSC under certain reverse bias conditions. When one cell in the series connection in a module is shaded, the current will ... Read more
Dye solar cells: a different approach to solar energy

Author: Le Roux, Lukas J ; Hietkamp, S ; Cummings, F Date: Nov 2008 An attractive and cheaper alternative to siliconbased photovoltaic (PV) cells for the conversion of solar light into electrical energy is to utilise dyeadsorbed, large-band-gap metal oxide materials such as TiO2 to absorb the solar light. ...

Electro-Fenton Degradation of Selected Antiretroviral Drugs Using a Low-cost iron-modified carbon-cloth electrode

Author: Emej, IC ; Ama, OM ; Khoele, K ; Osifo, PO ; Ray, Suprakash S Date: Mar 2021 Human immunodeficiency virus (HIV) and acquired immune deficiency syndrome (AIDS) causes morbidity and mortality in infected patients. These epidemics are significantly reduced and treated globally with antiretroviral drugs (ARVDs). However, ... Read more
Influence of errors in the dimensions of a switched parasitic array on gain and impedance match

Author: Mofolo, MRO ; Lysko, Albert A ; Clarke, WA Date: Sep 2012 The dimensions of an antenna system defines its performance. This implies proper calibration and fabrication process are vital. Thus, there is a need to investigate the influence of the variations in the dimensions of the antenna on its ... Read more
