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.

Kovsies raise their voices to say no to racism – and yes to equality

Launch of the No-to-Racism/Yes-to-Equality Campaign : Video 

In support of National Human Rights Month, the UFS has launched the No-to-Racism/Yes-to-Equality Campaign. Through this campaign, the entire UFS community reaffirms its commitment to equality, respect, democracy, social justice, humanity, dignity, human rights, and diversity.

The first leg of the campaign, No-to-Racism, was launched at the Qwaqwa, Bloemfontein and South Campuses during the past month. “Look in the mirror tonight and have a discussion with yourself,” Prof Jonathan Jansen, Vice Chancellor and Rector of the UFS, said during the launch at the Bloemfontein Campus. “Ask yourself to what extent can I truly say, ‘I am dealing with my racism, my bigotry, my ethnicism, my homophobia, my xenophobia? Am I truly dealing with those in my life?’”

Through the No-to-Racism Campaign, staff and students are encouraged to take a public stand against not only racism, but also homophobia, sexism, ableism, xenophobia, classism, ethnicism, ageism, and all forms of intolerance and othering.

The start of No-to-Racism will closely be followed by the Yes-to-Equality Campaign, which will be launched on 1 April 2015.

SRC President, Mosa Leteane, urged the Kovsie community to make South Africa work. “We say ‘no’ because we want to say ‘yes’. Fix your ‘no’ so that your ‘yes’ is clear, it’s equal, it’s honest. That is what ‘yes’ looks like.”

The campaign is also aligned with the declaration made by the UFS Council in November 2014 in which it was stated that “the Council of the University of the Free State believes very strongly in the human dignity, equality, and freedom of all people. Accordingly, the Council reaffirms its abhorrence of acts of racism, sexism, and unfair discrimination of any kind or in any form”.
The No-to Racism/Yes-to-Equality Campaign is an initiative of the Institute for Reconciliation and Social Justice, together with the SRC.

Important dates:
1 April 2015: Launch of Yes-to-Equality Campaign on the Qwaqwa and Bloemfontein Campuses
13 April 2015: Pledge of the UFS community at 12:45 on the Red Square, Bloemfontein Campus
