The sun is the most important source of renewable energy today. Producing energy from sunlight using cheap, abundant and non-toxic materials is considered a major challenge in the field of solar-electrical energy conversion. ...
Perovskite-based solar cells (PSC) is the fastest growing solar technology to date since inception in 2009. This technology has invigorated the photovoltaic (PV) community. While it has taken 15-42 years for traditional ...
Dye sensitized solar cells (DSSCs) have attracted rapid interest over the recent years with prospect of emerging as a viable alternative to conventional silicon based solar cells. The photoanode of DSSCs comprises of dye ...
The knowledge of solar radiation in this dispensation is crucial. The lack of grid lines in the remote rural areas of South Africa necessitates the use of solar energy as an alternative energy resource. Solar radiation ...
Currently the dye sensitized solar cells have attracted more attention due to their low cost, transparency and flexibility. These types of solar cells use the dye molecule adsorbed on TiO2 semiconductor in Nano architecture ...
Titanium dioxide (TiO2) is considered to be an ideal semiconductor for photocatalysis because of its high stability, low cost and safety towards both humans and the environment. Doping TiO2 with different elements has ...
Understanding how and why superconductivity (SC) occurs in a given material has been
very challenging for physicists for more than a hundred years, notwithstanding the major
milestones, such as the London theory, the ...
Since the discovery of water photolysis on a TiO2 electrode by Fujishima and Honda
in 1972, TiO2 has attracted extensive attention as an ideal photocatalytic material
because of its excellent properties such as high ...
This is the first study to investigate the impact of working capital management on the performance (profitability and value) of South African firms listed on the Johannesburg Securities Exchange (JSE) before, during and ...
