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 responds on the outcome of the court case in the alleged attack by Cobus Muller and Charl Blom on Gwebu
2014-09-09

The management of the University of the Free State (UFS) acknowledges the finding issued on 4 September 2014 by the South African Human Rights Commission (SAHRC) that it was “unable to find any corroborating evidence to make a conclusive finding of racism and violation of human rights” in the Muzi Gwebu case.

The university management also takes cognisance of the ruling in the Bloemfontein Regional Court by Regional Magistrate Rasheed Matthews today (9 September 2014) that both Cobus Muller and Charl Blom are found not guilty on all the charges which included reckless driving, crimen injuria, attempted murder and assault (Muller), and a charge of assault (Blom). We note the Magistrate’s concerns about “inconsistencies in the evidence and exaggerations”, that the complainant “displayed hostility throughout the trial” and that he was “not a reliable witness and is prejudiced.” And therefore, in the words of the Magistrate to the defendants, “I’ve decided to give you the benefit of the doubt.”

Both Muller and Blom were suspended from all campuses of the UFS on 19 February 2014 based on the evidence available at the time of reckless driving, assault and other charges. This evidence was further borne out by an internal investigation into the incident of 17 February 2014 on the Bloemfontein Campus. In the light of the evidence available to us at the time, and the volatile situation on campus in the days following the attack, the UFS management believes that it was the correct decision to suspend the students, given the serious nature of the charges, and pending a decision of the courts.

In the light of both the SAHRC ruling as the Regional Court ruling, the university management has decided to take the following steps:

1.    The suspensions of both Muller and Blom from all campuses of the university are lifted with immediate effect.

2.    Muller may attend a forthcoming graduation ceremony during which the degree BSc Construction Management will be officially conferred upon him. He completed all the requirements for the degree in 2013, but was not allowed to attend the graduation ceremony of 11 April 2014 due to his suspension and the fact that the criminal charges were still pending.

3.    Blom may return to the university to complete his studies.

4.    The UFS is in discussion with the parents of one of the students and, if required, would also meet with legal counsel of the university, as well as those of students Muller and Blom to discuss any further steps given the outcome of the court case.

5.    In short, on grounds of the ruling by die SAHRC, as well as the Bloemfontein Regional Court, the university will not continue with its disciplinary action against Muller and Blom.

Prof Jonathan Jansen, Vice-Chancellor and Rector of the UFS said: “This has been a very difficult time for the university and I am pleased to record that throughout the crisis, the student body on the Bloemfontein Campus showed remarkable restraint and discipline, confirming also the broad, non-racial character of the peaceful protests that followed. Our student body has matured and our campus cultures are much more inclusive and transformed as a result of the quality and depth of student leadership over the past few years. The new Student Representative Council (SRC) is a splendid example of this – with the first black woman President (Mosa Leteane) and the first blind woman SRC student leader (Louzanne Coetzee).”

“I am pleased that the matter is now behind us and, again, we rest with the decisions of the Commission and the Courts as final,” he said.

Prof Jansen also apologised on behalf of the UFS to Cobus Muller and Charl Blom, their parents, and their families, for the disruption that the suspension brought in their lives and for the stress they had to bear during this difficult period. “For that, I am truly sorry,” he said.
