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.

Top PhD graduates hailed for excellent research in development and historical studies

 Description: Top PhD graduates hailed for excellent research  Tags: Top PhD graduates hailed for excellent research  

Prof Melanie Walker and Prof Ian Phimister

The Centre for Research on Higher Education and Development and the International Studies Group celebrated its PhD graduates on 26 June 2017. The four graduates were joined by their PhD promoters Prof Ian Phimister and Prof Melanie Walker, the Dean of the Faculty of Economic and Management Sciences, and their families, who came from far and wide, as well as various faculty academics and staff. Their areas of study ranged between Development Studies and Africa Studies, exploring issues that make a significant impact on the Southern African region and the continent as a whole.

In the Faculty of Economic and Management Sciences, specialising in Development Studies, Dr Faith Mkwananzi, promoted by Prof Merridy Wilson-Strydom, explored the lives and educational aspirations of marginalised migrant youth, a case study in Johannesburg. She focused on the complex nature of the daily lives and experiences of marginalised migrant youth and the complexities that influence the formation and achievement of educational aspirations in contexts of vulnerability and disadvantage. The study provides compelling evidence for policy and practice that can make the lives of marginalised young migrants better.

A focus on teaching and learning in Zimbabwean universities with a focus on quality as a human development, was what Dr Patience Mukwambo, put her research efforts into. Her work makes an original contribution to national, continental, and international debates on conceptualising and operationalising the quality of teaching and learning in higher education. She successfully developed a significant alternative approach to understanding what quality in higher education teaching and learning entails, the factors that influence the realisation of quality as she theorises it, and the overall importance for human development and human well-being in universities and society.

Dr Bothwell Manyonga, who also specialised in Development Studies, examined the broader debates on the purposes and practices of teaching and learning in higher education with a case study at two South African universities, with an emphasis on principles of social justice and equity. In the thesis, he developed a model that proposes grounds for (re)thinking sociology teaching and learning to address how the capabilities approach and dominant human capital theory might complement each other in higher education and curriculum development. This takes into account both the instrumental aim of employment, which is of concern to students, as well as the intrinsic goods of critical discourse and personal development.

In the Faculty of the Humanities, with a specialisation in Africa Studies, Dr Abraham Mlombo’s doctoral research explored the relationship between Southern Rhodesia and South Africa 1923-1953, examining the ‘special relationship’ between the two countries from the former’s perspective, highlighting the complexity of the ties between them by examining (high) political relations, economic links and social and cultural ties. “It is through Abraham’s research that for the first time, black experiences of both sides of the colonial border are detailed,” said Prof Phimister.

In congratulating the graduates, Prof Melanie Walker expressed that a lot of hard work was put into training the PhD candidates and they had without a doubt produced work that was of the highest level, at international standards.
