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.

Bloemfontein Campus hosts annual HELTASA conference
2014-12-09

This year, the privilege to host the annual Higher Education Learning and Teaching Association of Southern Africa (HELTASA) conference was afforded to our university. The event took place on the Bloemfontein Campus from 18 – 21 November 2014, attracting keynote speakers and members from across the world.

HELTASA is a professional association mainly for educators and significant role players in higher education institutions. With its inception in the early 2000s, it has grown to become the premier organisation for teaching and learning in Southern Africa, Dr Amanda Hlengwa, President of HELTASA, pointed out.

A central concern of this body is issues around success within the tertiary sector. The theme of this year, ‘Accessing success: using evidence for change’ served to focus members’ attention on what works and what does not work – as derived from researched evidence.

In a message from Prof Jonathan Jansen, Vice-Chancellor and Rector of the University of the Free State (UFS), he stressed that the task as university teachers “is not simply cognitive gains that ensure graduation success but also intellectual gains that ensure success in life during and after university studies.”

The conference was led by internationally-acclaimed keynote speakers, namely Prof George Kuh, Prof William Grabe and Prof Fredricka Stoller, as well as our own A1 NRF-rated Prof Malanie Walker.

Prof Kuh is Adjunct Research Professor of Education Policy at the University of Illinois and Chancellor’s Professor of Higher Education Emeritus at Indiana University. In his keynote address, Prof Kuh offered valuable lessons from the field to promote student success.

Profs Grabe and Stoller collectively presented the second keynote address that explored how to set up students for success through strategic-reader training. Prof Grabe is Regents’ Professor of Applied Linguistics and Vice President for Research at Northern Arizona University. Prof Stoller is a Professor of English at Northern Arizona University, where she teaches in the MA-TESL and PhD in Applied Linguistics programmes.

Prof Walker is a Senior Research Professor at the UFS Centre for Research on Higher Education and Development (CRHED). She is also currently Director of Research Training and a senior researcher in the EU-funded Marie Curie EDUWEL project. In her keynote address, Prof Walker looked at well-being and agency in higher education.
