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.

SA-YSSP scholars attend high level colloquium with policy makers and research stakeholders

Scholars taking part in the 2nd Southern African Young Scientists Summer Programme (SA-YSSP), attended a one-week seminar hosted by the African Doctoral Academy at the Stellenbosch University, which concluded with a colloquium at the Stellenbosch Institute for Advanced Study.

This was part of the final leg of their three-month stay and studies at the University of the Free State.

This seminar was a capacity development intervention with the purpose of equipping SA-YSSP young scholars with the skills to communicate their research work effectively with different audiences.

The 36 scholars were hand-picked from some of the world’s most promising and top researchers to take part in the novel three-month programme for advanced doctoral candidates. Their research interests closely aligned with the Department of Science and Technology’s (DST) grand challenges and the International Institute for Applied Systems Analysis’ (IIASA) current research programmes regarding global environmental, economic and social change.

The SA-YSSP is an initiative that contributes to the establishment, growth and enhancement of high-level strategic networks internationally. At the same time it develops capacity in systems analysis at the PhD and supervisory levels through research conducted in the areas of the Department of Science and Technology’s (DST) grand challenges.

At the colloquium, students were expected to showcase their work and research according to their various fields of expertise. High-profile policy makers and policy funders, as well as academia and fellow researchers judged and critiqued the work.

Dr Priscilla Mensah from the UFS and co-director of the programme, says it is important for the young scientists to frame their findings in a way that will be relevant to policy makers and the public at large.

“The partnership with the African Doctoral Academy was crucial in this regard since it is a capacity development entity aimed at strengthening and advancing doctoral education, training and scholarship on the African continent. The objective of this week-long capacity strengthening intervention is to equip the young scientists to be able to communicate their research effectively with different audiences, including potential funders and policy makers.

“I am convinced that the young scientists will no longer view policy makers as abstract entities, but as stakeholders who must be engaged to facilitate implementation of evidence-based policy.”

Dr Aldo Stroebel, Executive Director: International Relations and Cooperation, National Research Foundation, says the purpose of the colloquium is to bring together different sectors in one room to look at different challenges holistically, with an emphasis on systems analysis for a common goal.

The SA-YSSP forms part of an annual three-month education, academic training and research capacity-building programme jointly organised by IIASA, based in Austria, the National Research Foundation (NRF) and the DST. IIASA is an international research organisation that conducts policy-oriented scientific research in the three global problem areas of energy and climate change, food and water, and poverty and equity. South Africa’s engagements with IIASA, specifically with regard to the SA-YSSP, relate primarily to the DST’s Ten-Year Innovation Plan.

The UFS is the first institution outside Austria to host the summer programme. Researchers in the programme are, among others, from South Africa and the rest of the African continent, the USA, the Netherlands, India, Hungary, Austria and Germany.
