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.

New generation must take South Africa into the Promised Land

Former President Nelson Mandela was part of the Moses generation that took people out of bondage. What the country now needs is the Joshua generation that will take it into the promise land.

This is according to political analyst and public commentator, Prof. Somadoda Fikeni. He was speaking to staff and students participating in the Global Leadership Summit, which took place on the Bloemfontein Campus from 8-20 July 2012. Prof. Fikeni took part in a panel discussion on Justice and Reconciliation. He and other panellists observed that there were still many challenges facing reconciliation in South Africa.

Referring to controversial statements made by Helen Zille, Julius Malema and Pieter Mulder, Prof. Fikeni said public discourse had become toxic and that the country was faced by a leadership crisis.

Ms Yasmin Sooka, a former Commissioner of the Truth and Reconciliation Commission (TRC) and Executive Director of the Foundation for Human Rights South Africa, asked if reconciliation had not come at the expense of redress. She said that to date there had been no restitution.

Ms Lihlumelo Toyana, a post-graduate student at the university, was also part of the panel. She told the audience that 18 years into democracy, there are still people waiting for justice. Toyana said young people hoped to see change and wondered if South Africans would ever sit down and have dialogue about the past. “We need closure; we need to take the country forward.”

The other panelists were lawyer, politician and former Human Rights Commissioner Prof. Leon Wessels; a professor from the University of Cape Town’s Law Faculty, Prof. Jaco Barnard-Naude; and psychologist, Prof. Alain Tschudin.
