With a constant increase in the price of electricity, any innovation to replace this necessity in our daily lives is welcome. 

The University of the Free State (UFS), whose vision is supported by an element of innovation, welcomes the recent agreement between its Department of Physics and Ghent University.

Attractive solution

Not only will this research – which aims to develop the materials necessary for transparent solar panels – enlarge the international research footprint of the UFS, but it is also an attractive solution to address the energy demands of buildings, electric motor vehicles, and mobile electronics without affecting their appearance.

According to Prof Hendrik Swart, from the UFS Department of Physics, the agreement between the two universities entails a joint doctoral degree in which both universities will supervise the project and the awarding of the doctorate. The student, Lucas Erasmus, will conduct research at both institutions.

Transparent solar panel

The idea with the research is to develop glass that is transparent to visible light, just like the glass you find in the windows of buildings, motor vehicles, and mobile electronic devices. However, by incorporating the right phosphor materials inside the glass, the light from the sun that is invisible to the human eye (ultraviolet and infrared light) can be collected, converted, and concentrated to the sides of the glass panel where solar panels can be mounted. This invisible light can then be used to generate electricity to power these buildings, vehicles, and electronic devices. The invention is therefore a type of transparent solar panel.

Implemented in cellphone screens

This technology can be implemented in the building environment to meet the energy demands of the people inside the buildings. 

The technology is also good news for the 4,7 billion cellphone users in the world, as it can be implemented in the screens of cellphones, where the sun or the ambient light of a room can be used to power the device without affecting its appearance. 

Another possible application is in electric cars, where the windows can be used to help power the vehicle.

Low-income housing

Erasmus added: “We are also looking at implementing this idea into hard, durable plastics that can act as a replacement for zinc roofs.” 

“This will allow visible light to enter housing, and the invisible light can then be used to generate electricity. The device also concentrates the light from a large area to the small area on the sides where the solar panels are placed; therefore, reducing the number of solar panels needed and, in return, reducing the cost.”

The technology will take about a decade to implement.

“This study is currently ongoing, and we are experimenting and testing different materials in order to optimise the device in the laboratory. After this, it needs to be upscaled in order to test it in the field. It is truly the technology of the future,” said Erasmus.

Education is the key to the unification of black and white masses of South Africa

In view of the divisive nature South Africa’s (SA) schooling system during the pre-1994 period, education appears to be one of the most potent unifying mechanisms of the democratic dispensation. With the elimination of Bantu education and the subsequent gain of access to basic and higher education by the historically-disadvantaged of this country, the schooling system is said to be building and reconstructing bridges which were burnt by the apartheid administration.

This opinion was shared by Dr Mafu Rakometsi, Chief Executive Officer (CEO) of UMALUSI – the Council for Quality Assurance in General and Further Education and Training. Dr Rakometsi, a University of the Free State alumnus, presented a guest lecture titled: “Educational transformation in South Africa – lessons for the future” on Thursday 5 November 2015 at the Bloemfontein Campus.

The discussion of salient matters regarding education and transformation was hosted by the Faculty of Education in collaboration with Institutional Advancement: Alumni.

According to Dr Rakometsi, the transformation of education in SA can be viewed in the same light as that of government; where the nationalist policy was succeeded by democracy. “Education promoted the agenda of ensuring that there was no integration of the South African population,” he said of the past.

“Simply put, in SA, the black person was denied, and deprived of, human rights,” he added. Nonetheless, the declaration of human rights as enshrined in our constitution, and the conviction held by lobby groups, such as the Black Sash, that the young should seek and receive education led to transformation within the education sector.

Although that transformation has been accomplished, poverty continues to hinder access to education. Approximately 80% of the black students in higher education are from poor families, meaning that their parents are unable to fund the completion of their studies. Financial exclusion then translates to social exclusion, which relegates these underprivileged students into narrow enclaves. This results in a counter-transformation situation as a consequence.
