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.

Paying homage to a music maestro

American singer, songwriter, composer and actor, Thomas Alan Waits (1949–), has been a major inspiration to artists, musicians, poets, writers and thinkers for almost 40 years. He is considered as one of the godfathers of grunge and poetic rock and is a master of contemporary narrative –able to weave emotion and intrigue into his stories of urban grit and rural abandonment. His sometimes jaundiced view of the underbelly of society serves as a rich source of visual imagery.

The Johannes Stegmann Art Gallery is celebrating this vanguard with the exhibition Tom Waits for No Man.

Gordon Froud, artist and senior lecturer at the Department of Visual Arts at the University of Johannesburg (UJ), curated and toured with the Leonard Cohen exhibition entitled Altered Piecesin 2011 and 2012. Due to the success of that exhibition, Froud decided to extend his curative activities in the direction of Tom Waits.

This exhibition is based on a roughly LP-sized circular format (30cm in diameter). Most works hang on the wall, but some artists that preferredto work in 3D, made use of the disc as a base or platform on which to build. There was no restriction on materials or approach. There was no process in selection of songs and each artist was free to use whichever lyric or section of lyrics that they choose (even if someone else had selected this too – artists seldom come up with the same solutions).

The exhibition was launched at the ABSA KKNK in April 2013 and has travelled to the UJ Art Gallery and Grande Provence Wine Estate for the Literary Festival.

The exhibition is on display at the Johannes Stegmann Art Gallery until 25 October 2013.

Gallery hours: 08:30 – 16:30, Monday – Friday
