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.

NBC tells Wayde’s story

The Kovsie star Wayde van Niekerk stands an excellent chance of shining at the 2016 Olympics and has a remarkable story behind his success.

This is why NBC Olympics, a division of the American broadcasting network NBC, selected the athlete from the University of the Free State (UFS) to do a special insert for the Olympics in Rio de Janeiro.

A film crew from NBC visited the City of Roses and the Bloemfontein Campus of the UFS on Monday 26 and Tuesday 27 October 2015 to film the insert. The feature will be screened on NBC Olympics’ platforms during and leading up to the Olympics next year.

One of four stars

Van Niekerk was one of four athletes used by the crew to film inserts on. The others were the South African swimmer Chad le Clos, the Kenyan 800 m athlete David Rudisha, and Ethiopian middle- and long-distance athlete Genzebe Dibaba.

The crew interviewed Van Niekerk and his coach Ans Botha, and also paid a visit to Pellies Park during one of his training sessions.

According to Tom Davidson, feature producer at NBC Olympics, the piece about Van Niekerk will be about three minutes long.

“We do a pretty good job of picking good stories, but it is up to the athletes to get there,” Davidson said.

“We think Wayde has a good shot at being in the finals of the 400 m at the Olympics.”

Van Niekerk won a gold medal in a time of 43.48 s at the World Championships in Beijing during August 2015 and set a new South African record for a third time and a new African record for a second time this year in the process.

Beijing success propels Wayde onto NBC radar

“Wayde’s performance in Beijing certainly propelled him onto our radar,” said Davidson.

 “He beat former World and Olympic champions like Kirani James and LaShawn Merritt.”

He feels that Van Niekerk is also very young and still at university.

And Botha makes his story even more interesting.

“It is not every day that you see a 74-year old great-grandmother coaching a world champion.”
