Application of TiO2 nanotubes in dye-sensitised solar cells for improved charge transport

Author: Cummings, F Date: Sep 2010 A major breakthrough in reduction of cost of photovoltaics was realised in 1991, with the first report of a functioning photoelectrochemical cell. This resulted in heightened interest from the industry and science community. This presentation ... Read more
Dye solar cells ( and PV's) in South Africa

Author: Le Roux, Lukas J Date: Feb 2006 Various institutions are doing research on photovoltaics in South Africa. Although the CSIR is the only one that does research on DSC's there is significant support from the different universities. In the presentation a short overview of the ... Read more
Energy Storage

Author: Bladergroen, B ; Bischof-Niemz, T Date: Oct 2015 With the emergence of variable renewable energy (VRE) sources, such as solar photovoltaics (PV) and wind power, flexibility requirements in the power system are generally increasing. However, what is not so clear yet is what “increasing ... Read more

Impact of measured spectrum variation on solar photovoltaic efficiencies worldwide

Author: Kinsey, GS ; Riedel-Lyngskær, NC ; Miguel, A ; Boyd, M ; Braga, M ; Shou, C ; Cordero, RR ; Duck, BC ; Maweza, Elijah L ; Pratt, Lawrence E Date: Aug 2022 In photovoltaic power ratings, a single solar spectrum, AM1.5, is the de facto standard for record laboratory efficiencies, commercial module specifications, and performance ratios of solar power plants. More detailed energy analysis that ... Read more
Low-cost transparent solar cells: Potential of TiO2 nanotubes in the improvement of these next generation solar cells

Author: Cummings, F Date: Sep 2010 This paper provides a background to photovoltaics, and goes on to discuss dye-sensitised solar cell research and development at the CSIR. An overview of TiO2 nanotube synthesis is given, followed by the discussing the manufacturing process ... Read more
Optimal control of a fuel cell/wind/PV/grid hybrid system with thermal heat pump load

Author: Sichilalu, S ; Tazvinga, Henerica ; Xia, X Date: Oct 2016 This paper presents an optimal energy management strategy for a grid-tied photovoltaic–wind-fuel cell hybrid power supply system. The hybrid system meets the load demand consisting of an electrical load and a heat pump water heater supplying ... Read more
Photovoltaic research and development

Author: Cummings, F Date: Sep 2009 Photovoltaic (PV) is the direct conversion of sunlight into electrical energy through a solar cell. This presentation consists of an introduction to photovoltaics, the South African PV research roadmap, a look at the CSIR PV research and ... Read more
TiO2 nanotube-based dye solar cell research in South Africa

Author: Cummings, F ; Le Roux, Lukas J ; Mutangwa, N ; Knoesen, D Date: Oct 2009 Vertically orientated titanium dioxide (TiO2) nanotubes hold great potential for application in dye-sensitized solar cells (DSCs) as they provide an unscathed, one-dimensional transport route for photo-generated charge carriers, thereby ...
