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.

Lecture by Judge Albie Sachs: ‘Sites of memory, sites of conscience’
2015-03-23

Judge Albie Sachs

Human rights activist and former Constitutional Court Judge, Albie Sachs, will deliver a public lecture on the Bloemfontein Campus. The topic of his discussion will be ‘Sites of memory, sites of conscience’. This lecture will form part of a series that focuses on how the creative arts represent trauma and memory – and how these representations may ultimately pave the way to healing historical wounds.

The details of the event are:
Date: Thursday 26 March 2015
Time: 12:30
Venue: Albert Wessels Auditorium, Bloemfontein Campus
RSVP: Jo-Anne Naidoo at Naidooja@ufs.ac.za
A South African Sign Language interpreter will be present at the event.

Joining Judge Sachs on stage as respondent will be Dr Buhle Zuma, a young scholar and lecturer at the University of Cape Town's Psychology Department.

Expressing experiences of trauma
Judge Sachs is no stranger to the use of the arts as a way of expressing the inarticulable and overwhelming experiences of trauma. Targeted as an anti-apartheid freedom fighter, he lost his right arm and was blinded in one eye in a car bomb attack in 1988. As a judge of the Constitutional Court, he spearheaded conversations about the role of the arts in our constitutional democracy. This has led to the installation of some of the best artworks by South African artists at the Constitutional Court.

Vice-Chancellor’s Lecture Series on Trauma, Memory, and Representations of the Past
This lecture will launch of the Vice Chancellor’s Lecture Series on Trauma, Memory and Representations of the Past. It forms part of a five-year research project led by Prof Pumla Gobodo-Madikizela, funded by the Mellon Foundation. The event is hosted by the UFS Trauma, Forgiveness and Reconciliation Studies.

“One of the most remarkable aspects of trauma,” Prof Gobodo-Madikizela says, “is the loss of language, a moment of rupture that produces what some scholars have referred to as ‘speechless terror’. The arts, in all its forms – literary, performance, and visual – are a viable mechanism through which the unspeakable, traumatic past may be represented.”

These artistic forms of representing trauma are at the heart of this Vice-Chancellor’s Lecture Series. “We are interested not only in how experiences that transcend language are represented through the arts,” Prof Gobodo-Madikizela explains, “but also in probing the limits of trauma theory, and how the creative arts might be employed to bear witness in a way that may open up the possibility of healing.”

Dr Buhle Zuma
Former Mandela Rhodes scholar and one of the 2011 Mail & Guardian’s 200 Young South Africans, Dr Zuma is particularly interested in issues at the heart of our rainbow nation. His current research revolves around the question of freedom: what it means to be human for black people after centuries of dehumanisation, and the role of desire and fantasy in the political imagination of post-apartheid South Africa.
