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 hosts first ACS Institute held on African soil
2015-12-08



The first ever Association for Cultural Studies (ACS) Institute hosted on the African continent is taking place on the Bloemfontein Campus. At the event are, from the left: Prof Jonathan Jansen, Vice-Chancellor and Rector of the UFS; Prof Jean Comaroff, Alfred North Whitehead Professor of African and African-American Studies and Anthropology at Harvard University; Prof Helene Strauss, Chair of the Department of English at the UFS; and Prof Gil Rodman, Chair of the Association for Cultural Studies and Professor of Communication Studies at the University of Minnesota.

The University of the Free State (UFS) is hosting the 2015 conference of the Association for Cultural Studies (ACS) Institute – the first time for this international event to take place on the African continent.

From 7 – 12 December 2015, some of the world’s leading scholars in cultural studies are taking part in the conference on the Bloemfontein Campus. The event has been organised by the UFS Department of English in collaboration with colleagues from other departments in the Faculty of the Humanities.

 The ACS is the foremost international association for scholars in cultural studies, and has been hosting the biennial Crossroads in Cultural Studies Conference since 2006. In 2011, the ACS held its inaugural institute at the University of Ghent (Belgium), followed, in 2013, by one at the Alpen-Adria University Klagenfurt (Austria). As the 2015 meeting of the institute is the first to be held in Africa, the organisers aim at highlighting the contributions that scholars from our continent and other (post)colonial contexts have made to cultural studies, even as it engaged many of the long-standing theoretical concerns generated for the field by scholars from the Global North.

Themed ‘Precarious Futures’, the conference explores how cultural studies might assist in charting more equitable futures by reflecting critically on the cultural, economic, and political trajectories within which precariousness – a state increasingly anticipated for the planet – might be altered. Experts in a diversity of disciplines are sharing their perspectives in the form of seminars and lectures.

Keynote lectures are delivered by Prof Jean Comaroff (Harvard University), Prof John Erni (Hong Kong Baptist University), Dr Jo Littler (City University London), Dr Zethu Matebeni (University of Cape Town), and Prof Handel Kashope Wright (University of British Columbia).

In her opening lecture on Monday 7 December 2015, Prof Comaroff addressed the challenging relationship of law, detection, and sovereignty in contemporary African polities within the South African post-apartheid context.

Topics discussed include climate change; the archives of everyday life; cross-racial intimacies; ethnography; meritocracy; cultural studies and human rights; China and globalisation; gender, sexuality, and race; and governance, embodiment and the work of care.
