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.

But do you forgive yourself, Eugene de Kock? asks Candice Mama

Candice Mama and her family met with her father’s assassin. Eugene de Kock. Prime Evil. Commander of the apartheid government’s covert Vlakplaas police unit. And what followed from this meeting was one of our country’s most poignant gestures of reconciliation. One by one, each family member expressed their forgiveness of De Kock, and soon afterwards, he was granted parole.

Candice recently visited the Bloemfontein Campus to talk about ‘An Unexpected Encounter with Eugene de Kock: A Journey of Transformation’. The event was a collaborative effort between the Institute for Reconciliation and Social Justice and Trauma, Forgiveness, and Reconciliation Studies.

“What makes it possible to cross the boundary from loss and pain to bond with the person who hurt you?” Prof Pumla Gobodo-Madikizela, asked Candice. “I had to educate myself about the when, where, and how, to get a context for Eugene de Kock,” she answered. With the encouragement of her mother, Candice became an avid reader from an early age. She devoured information, so that she could build a picture of this man within a specific historical and political context. What also contributed to this moment of reconciliation for her was De Kock humbling himself and taking full responsibility for his actions.

This meeting was not without inner conflict for Candice, though. “Why am I crying for hím?” she asked herself as she listened to him speak. “Why am I laughing?” she chastised herself as De Kock preened shyly for a group photograph with the family. “Is there something wrong with me to connect with him?” She questioned her values and beliefs. But instead of a monster, Candice saw the true essence of a repentant human being.

But how do you know he didn’t fake it, many people asked. Because it was “one of the most sincere and honest encounters I’ve experienced,” she said. During their meeting, Candice saw a man “crushed by the world”. Everything he believed as a young man, he realised, was a lie.

“Do you forgive yourself?” Candice asked the one question De Kock feared most. And in that moment, he was humanised for her. “When you’ve done the things I’ve done,” De Kock replied, “how do you forgive yourself?”
It remains an open question. But this act of forgiveness gives an entire country hope.
