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 Department of Communication and Brand Management at the University of the Free State (UFS) has won two International Gold Quill Awards from the International Association of Business Communicators (IABC) for projects executed in 2016. “Winning two Gold Quill Awards put the entrant in the top ranks of the business communicators of the world,” said Ghrethna Kruger, IABC 2017 Quill Awards Chair South Africa.

The Department won Gold Quill Merit Awards for their entries of the publication, For such a time as this: A commemorative journey, and the communication process with prospective students through the Sound[W]right: UFS student tone and voice project.

Two Gold Quill Awards in 2017
This is the third time the department has received recognition by the IABC. In 2014, it received the Jake Wittmer Research Award, a Gold Quill Merit Award, and an Africa Gold Quill Award. In 2015 the department received an Africa Merit Award, Africa Gold Quill Merit Award, a Gold Quill Merit Award, and a Gold Quill Excellence Award. “I am very proud of the nine awards we have won over the past couple of years. Being recognised by a prestigious global association such as the IABC is a great honour. The fact that the UFS is the only tertiary education institution in the country to receive awards this year makes it even more special," said Lacea Loader, Director: Communication and Brand Management at the UFS.

With the 2017 IABC Awards the IABC has in total recognised 227 entries as world class, announcing 74 Excellence Awards and 153 Merit Awards. They represent a cross-section of public- and private-sector organisations, both large and small. This year there were 13 winners from South Africa compared to last year’s three winners.

Work reflects superior production values
Entries were evaluated against the IABC Gold Quill Awards criteria and IABC’s seven-point scale of excellence. Feedback from the IABC Gold Quill evaluators, on the publication, For such a time as this: A commemorative journey stated: “Exceptional effort and an excellent gift that celebrates your honoree and preserves school history. It demonstrates superior production values and strong images convey key messages.”

On the entry: Sound[W]right: UFS student tone and voice project, the IABC Gold Quill evaluators said: “This entry shows innovation, collaboration, persistence, generosity and strategic intent. They have accomplished much within a very limited budget, to the benefit of both the university and its students.”

“The Gold Quill Awards programme celebrates business communication’s best practices and the value professional, strategic communication programmes bring to an organisation’s bottom line, its brand and its reputation,” said Lynn Barter, ABC, MC, chair of the IABC awards committee. “Each entry is evaluated on its own merits against IABC’s Global Standard of excellence in communication. Winning a Gold Quill recognises exceptional work, innovation and creativity.

Taking communication to the next level
“Gold Quill winners represent a global community executing their responsibilities ethically and to the highest standards of the profession. These exemplary practitioners deliver high impact results for their organisations and clients, taking communication to the next level.”
