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.

The newly elected Chairperson of the UFS Council, Mr Willem Louw, and Prof Francis Petersen, the incoming Vice-Chancellor and Rector of the UFS, were welcomed at this year’s official opening of the academic year which took place at the Bloemfontein Campus of the University of the Free State (UFS) on 3 February 2017.  

Prof Petersen, who will start his tenure at the UFS on 1 April 2017, was introduced to staff by the Acting Rector, Prof Nicky Morgan. Prof Petersen shared his future plans for the UFS with staff.

His vision for the UFS spells excellence. Among others, he seeks to establish an academic culture of excellence, underpinned by the pillars of diversity and inclusivity. “It is important that there should be respect for different convictions,” he said.

“The UFS should be a place where everyone feels welcome; a strong sense of belonging is needed. Staff and students should feel that they would like to make a contribution to make the UFS a strong university,” he said.

In order to address the institutional climate issue, Prof Petersen suggests that attention be given to the curriculum as well as transformation of the research culture. Research outputs should be expanded and diversified. Inclusivity from a community engagement perspective is also needed. “The things we are good at and in which we excel should be the anchors impacting our academic enterprise,” he said.

In terms of the physical environment, he said that spaces should be welcoming for students. “It is important that we sit with students to get their views and listen to their concerns,” Prof Petersen said.

To promote transformation at the university, the UFS management team is busy working on an integrated transformation plan to be submitted to Council in June 2017. As part of this process, consultations will be held with staff and students in order to incorporate their perspectives and convictions in the plan as well.

“It is important that there should be
respect for different convictions.”

Furthermore, it is important for Prof Petersen that the Qwaqwa and South Campuses should be more integrated with the Bloemfontein Campus. “The UFS is one university with three locations. The fact that it is one university should be reflected in our actions, attentions, and thoughts. Although there are geographical differences, all three campuses should receive the same resources and should deliver the same quality outputs,” he said.

Prof Petersen ended his speech by returning to the importance of academic excellence. “With the Academic Project we always strive for excellence. To achieve academic excellence, the focus is on both academic and support staff. In order to reach our goal, all staff should produce work of superior quality,” he said.

“I am a good listener who is outcome driven, with a vision that includes: diversity, inclusivity, academic excellence, and innovation”, Prof Petersen concluded.
