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.

An article, co-authored by Kovsies’ own Miss World, Rolene Strauss, was published recently in a medical journal

The article, which deals with research on the incidence of multiple losses by children, was published in South African Family Practice.

The study was part of the third-year research project for medical students in our Faculty of Health Sciences. Rolene worked with fellow students, Leischen Branders, Mirandie Claassen, Darienne Saaiman, and Andrea van Staden. Prof Gina Joubert from the UFS’s Department of Biostatistics and Prof Hanneke Brits were the module and study leaders.

In this study, a number of cases involving Bloemfontein children experiencing loss, as well as their reaction to it, were examined.

They divided the incidents into categories in order to address the broad definition of ‘losses’.

Approximately 69% of the children in the study have experienced three or more instances of loss in their lives. About 29% of the children have experienced loss in the category Personal Loss (assault, chronic and terminal illness, amputation, malnutrition, disability, abortion, and miscarriage). The greatest number of losses occurred in the category Interpersonal Loss (87%). This group of children has had to deal with the death of one or more parents/caregivers, drug and alcohol abuse, domestic violence, divorce, homelessness, and instability. In the category, Environmental Loss, xenophobia, unsafe living conditions, inadequate support, poverty, and unemployment were looked at. A total of 82% of the children in the group have experienced losses.

Prof Hanneke Brits, study leader of the group, says the extent of multiple losses by children is a topic that hasn’t been investigated widely.

“The study shows that children should receive special attention in order to help them process the trauma. Supportive care and inter-professional services play a major role in this regard.”
