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.

Cultivating excellence and success through academics

More than 130 delegates are gathering for the Golden Key, South African Summit at the Bloemfontein Campus of the University of the Free State (UFS). Golden Key International Honour Society recognises academic excellence and uses knowledge to transform lives. It has 400 chapters in eight countries. Of South Africa’s 12 chapters, 11 were present at the summit.

Prof. Driekie Hay, Vice-Rector: Academic at the UFS, welcomed delegates from the respective chapters. She commended them for their perseverance and dedication to excel. “Your academic aspirations and commitment contribute to cultivating a culture of excellence. It will provide a better future for every South African citizen,” she said. Prof. Hay challenged delegates also to “act” by turning their knowledge into actions to advance not only themselves but also society. She also urged them to “discover” everything about themselves, their chosen disciplines, allies and oppositions. “Mostly, you must internalise the spirit of lifelong learning,” she said.

Mr Ryk Neethling, Olympic gold medallist and businessman, was the first keynote speaker. He took everyone through the steps that ultimately led to the moment of victory for him and his team. “We found a way to compete with heart and determination in the 2004 Olympic Games. We were prepared and we took everyone by surprise. “To achieve what one has set one’s mind to, we must dream big,” he said. “Play your part in the team and be confident. Remember that you are victors and not victims,” he urged. He further emphasised the importance of making one’s own luck and, most of all, never to give up.

Another speaker for the summit includes Ms Peggy-Sue Khumalo, former Miss South Africa. Dr Derek Swemmer, Registrar (UFS) will present a workshop on Strategic Action Planning.

This event is the first external lecture that is presented in the Metro’s found in the new Health Sciences Building on the Bloemfontein Campus of the UFS.
