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.

Bloemfontein’s Visser brothers to wow hometown fans

South Africa’s YouTube singing sensation, Vicus Visser, will wow Bloemfonteiners on 18 April 2013 with a musical performance at the University of the Free State.

He and his talented brother Vincent will perform at the Wynand Mouton Theatre giving their hometown fans a taste of their recent performances in the United States. Vicus, who has been dubbed Bloemfontein’s Justin Bieber, performed overseas for the first time in February this year when he and his brother performed at events for Black History Month in Washington DC and New York. One of their performances was at the Kennedy Centre in Washington DC where they paid tribute to Nelson Mandela and Martin Luther King.

Vicus rose to fame in 2010 when a music clip of him as a ten year old boy, singing “These Arms” by All for One, appeared on the internet. After a massive seven-year search on social media channels by local and international record companies, he was tracked down to Heidedal in Bloemfontein. Vicus and Vincent moved to Johannesburg in 2012 where they were managed and mentored by Gareth Cliff, top radio presenter and judge on Idols South Africa.

Gareth will join the Visser brothers in Bloemfontein on 18 April and will be master of ceremonies at the concert titled Singing the Dream for South Africa - The Kennedy Centre Performance. As with their performance in the United States, the brothers will treat the hometown crowd to a selection of songs in English, Zulu, Sesotho and Afrikaans.

Vicus, Vincent and Gareth will also make special appearances at the two graduation ceremonies hosted at 09:30 and 14:30 on 18 April 2013. Gareth will be guest speaker and the two brothers will give a short performance. They will also have a meet and greet session with students at the Thakaneng Bridge at 11:45.

Tickets for the Singing the Dream for South Africa - The Kennedy Centre Performance cost R 20 and are available at Room 5, Thakaneng Bridge. The show starts at 19:30.
