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.

UFS receives R10 million in student funding from Absa

In support of building a more equitable and prosperous Africa, and in response to the plight of students who lack financial aid at universities across the country, Absa Bank handed over a cheque of R10 million to the University of the Free State (UFS) at a ceremony held on the Bloemfontein Campus on 13 June 2017 by the office of Institutional Advancement. The allocation of these funds will assist students who meet the bursary programme criteria (proven financial need, students who are from households with a combined income of less than R1 million per annum, with an academic average of 55% or higher).

Corporate and higher education collaborate
Speaking at the event, Rector and Vice-Chancellor of the UFS Prof Francis Petersen highlighted the important role corporates play in collaborating with educational institutions to help support future professionals who are the future builders of the economy and will later lead industry. “Absa and the UFS enjoy a good relationship and it is our hope that this bursary programme will grow from strength to strength,” he said.

In 2016 alone, Absa Bank disbursed R12 million towards settling outstanding fees for 439 students in four faculties of the UFS. In 2017 the funds will be allocated similarly to cover financial needs of qualifying students. Mr Bertie Smith, Absa Management Executive: Central Region said: “The university plays an important role in building future leaders and Absa’s strategy of shared growth supports the focus on education.”

Responding to a greater socioeconomic need
The event was attended by staff of the UFS and delegates from the Absa group, as well as students who were beneficiaries of the Absa Bursary Fund in 2016. Mr Fikemini Dlamini, Absa Head: Public Sector Business Banking, said the bursary programme was born out of the growing need to fund and develop the education of young people, and is a response to the outcry from students across the country in the “Fees Must Fall” movement. He said: “Educating one young person has a knock-on effect that has the potential to alleviate poverty in many families and communities around us.”
