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.

“When I came to the University of the Free State (UFS), all I had was a R50 note and I did not know how I was going to register.” This is what Bloemfontein Campus SRC President, Asive Dlanjwa, encountered when he arrived at the UFS. He says the biggest struggle for students is not having finances for registration at the beginning of the year.

R2 million to be raised for 2018 registration
It is for this reason that Dlanjwa will be partaking in the Right to Learn Cycle tour challenge from 27 November to 4 December 2017. The Student Representative Council (SRC), in partnership with Institutional Advancement, came up with this initiative to cycle from Bloemfontein to Cape Town in eight days in an effort to raise R2 million for 2018 registration.

Bringing hope to prospective students and their families
Dlanjwa says, “We want to give access to as many students as possible. This initiative is not only about the students, it’s about giving hope to their families and taking them out of poverty.” He recalls an incident where a student went to the SRC offices to seek help at the beginning of the year, with nothing but an identity document and the clothes he had on. The student had been sleeping at the Bloemfontein Tourism Centre because he had no money for accommodation and registration. “These are the types of cases that we have to deal with at the start of each year,” says Dlanjwa.

He urges the community to partner with them in ensuring that many students get access to higher education by donating money through the Give-n-gain page. Dlanjwa, joined by a few more guest cyclists, left Bloemfontein on Monday 27 November 2017 and are expected to arrive in Cape Town on Monday 4 December 2017.
