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.

  Varsity Netball match: YouTube video

The University of the Free State (UFS) recorded a superb 71-36 victory over the University of Johannesburg (UJ) in their Varsity Netball match in the Callie Human Centre on the Bloemfontein Campus.

At the end of the first quarter the home side was off to a good start leading 18-11. Yet UJ recovered well hereafter to close the gap by winning the second quarter and taking over with a 28-22 lead.

However, a string of scoring just after half-time saw the UFS cruise to a comfortable 52-28 lead as they went into the final quarter, resulting in a bonus-point victory in the end. UJ could only manage eight goals in the last period as they fell short of a consolation bonus point.

Kovsies lost their first match in the Varsity Netball tournament against NWU Pukke, but recovered well by beating Tuks and TUT respectively in the following clashes. Over the next fortnight the team from the UFS will have two more Monday night match-ups in the Callie Human Centre in Bloemfontein. They will face the University of Cape Town (UCT) on the court next week, followed by Stellenbosch University (Maties) the week thereafter.
