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.

International delegates attending the 5th Annual Commonwealth Teacher Research Symposium held at the University of the Free State (UFS) in Bloemfontein this week unanimously agreed that more research still had to be done on issues of recognition, registration and standards affecting teachers and teaching across Commonwealth countries.

This two-day gathering of researchers, officials and representatives of regional international organisations and higher education institutions agreed that issues of teacher migration, the professionalism of teachers, teacher preparation and the use of teaching standards, as well as the comparability and recognition of teacher qualifications should be further researched.

The delegates agreed on the following based on the research and data that were presented and shared with all the participants:

Teacher migration is recognised as an increasing global phenomenon that requires ongoing research in the Commonwealth.
Recognising that inequalities and differences within and across Commonwealth countries exist, and considering that fair and ethical treatment in the international recruitment of teachers is an important cornerstone of the Commonwealth Teacher Recruitment Protocol.

Teacher training, the recognition of teacher qualifications, the professional registration of teachers and the development of professional teacher standards should be actively encouraged through ongoing pan-Commonwealth research.

An increased acknowledgement of the role of the professionalisation of teachers through an improved understanding of teacher qualifications and standards.
There should be a specific research focus on teacher preparation and the use of teaching standards.

An increased comparability and recognition of teacher qualifications across Commonwealth countries should be actively encouraged.
Advocacy of teachers’ rights, effective protection of the vulnerable teacher, and appropriate strategies should be promoted to uplift the status of teachers and teaching as a profession.

The Commonwealth Teacher Recruitment Protocol, amongst other things, aims to balance the rights of teachers to migrate internationally against the need to protect the integrity of national education systems, and to prevent the exploitation of the scarce human resources of poor countries.

Delivering his keynote address at the symposium, the Rector and Vice-Chancellor of the UFS, Prof. Jonathan Jansen, decried the quality of professional qualifications in South Africa.

“We have become very good at manufacturing outcomes. We actually have become very good at giving an impression of having achieved particular outcomes without having achieved them at all,” he said.
“So what does it mean to talk about outcomes in an unequal country with unequal resources? What does it mean to talk about qualifications when we do not trust the outcomes?”

He suggested that the teaching profession should be subjected to a peer review mechanism and that the practice of setting minimum standards should be dealt away with because it results in minimum outcomes.

Dr Carol Anne Spreen, lecturer at the University of Maryland in the USA, proposed that countries should improve the quality of their own teachers instead of importing teachers from other countries.

The research symposium was organised by the Commonwealth Secretariat and hosted by the South African Qualifications Authority (SAQA) and the UFS.
