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.

School of Medicine not closing
2009-10-22

There is no immediate threat that the University of the Free State’s (UFS) School of Medicine will be closing.

This was confirmed by Prof. Gert van Zyl, Head of the UFS’s School of Medicine and acting Dean of the Faculty of Health Science, following media reports that Prof. Andries Stulting has indicated in a meeting with other medical schools and parliamentary standing committee members that the School will have to close due to the serious problems in the health sector.

“This discussion should be seen in context. Prof. Stulting, in his capacity as acting Head of the School of Medicine, and on behalf of the School and the Faculty, sent a proactive warning to the Free State Health Department, the Member of the Executive Committee and the Premier of the Free State regarding the long-term consequences of the health crisis. This statement was not interpreted correctly. Everything that Prof. Stulting said has already been included in the position statement that the School released in May 2009. What is urgent, though, is that the problems that were identified at especially Pelonomi Hospital in May this year were still not addressed,” said Prof. Van Zyl.

According to Prof. Van Zyl, problems at Pelonomi Hospital include not enough beds, lack of funding for the health sector in the Free State and in some instances problems with filling vacant positions.

“Some of these problems have already been addressed by the Free State Department of Health. Our training platform includes not only Pelonomi Hospital, but also Universitas Hospital, National Hospital, the Free State Psychiatric Complex and several clinics in the Bloemfontein area. This means that there are other facilities available that function in order to provide appropriate training to undergraduate students. Therefore, training is not in immediate danger and the School will definitely not be closing,” he said.

“New first-year students will start their studies in 2010 and I can assure you that there will be adequate training opportunities to take in and train students. However, we do struggle with a bigger intake as requested by Government. I want to put Prof. Stulting’s remark in context: He referred to postgraduate students and therefore the specialists who are in training,” said Prof. Van Zyl.

According to Prof. Van Zyl the specialists in training is a problem that was discussed with the Free State Health Department – with specific reference to less time in operating theatres and the number of beds at Pelonomi Hospital. “We are of the opinion that, should the Department address this problem as a matter of urgency, there will be no long-term damage to the training of these specialists in training. These are the students that Prof. Stulting was referring to,” he said.

The School received more than 1 500 applications for undergraduate studies in 2010 – all of these applications met the minimum selection requirements for the 140 available places. “Our current undergraduate students are therefore not influenced and they will continue to receive the quality training for which the School is renowned,” he said.

Prof. Jonathan Jansen, Rector and Vice-chancellor of the UFS, is aware of this and he satisfied himself as to the situation when he visited the hospitals in Bloemfontein on Friday, 9 October 2009. The national Minister of Higher Education and Training, Dr Blade Nzimande, was also informed of the School’s concerns when he visited the UFS in September 2009.
