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.

Prof John Grider, Associate Professor of History at the University of Wisconsin-La Crosse in the USA and a Research Fellow in the Institute for Reconciliation and Social Justice (IRSJ) at the University of the Free State (UFS), has launched a book based on more than a decade of research into the Pacific maritime labour identity. His monograph, entitled A Foreign Voyage—Pacific Labour Identity, 1840-1890, delves into the history of the maritime industry, not only as a vehicle for expanding the processes of capitalism, colonialism, industrialisation, and globalisation, but is also exploring the impact of this industry on the shifts in gender, race, class, and technology.

As a student in Colorado, a homesick Grider tried to connect with his coastal roots via research. “Before I started to explore the maritime history, I thought of the ocean as a type of boundary that you sometimes need to cross. The truth is that globalisation happens on ships.” Prof Grider’s passion for Pacific maritime labour identity generates colourful discussions on the topic. Masculine sailors confronted by technological de-skilling that corroded away their identity, come to life as he talks and writes. “I try to show students that history is more than a story about the powerful few, and that everyday people, who may seem powerless, play a major role in shaping the past and the future.”

This monograph is based on first-hand, previously unpublished accounts of daily life at sea, often from ships’ logs and the diaries kept by the men who sailed them. The culmination of much painstaking research and supporting evidence, this book investigates the complex interplay between gender, class, and race sourced from the narratives of men who found themselves working in the transforming Pacific maritime industry during the mid-nineteenth century. A powerful lesson to be learnt from this fascinating segment of maritime labour history, is adaptability, “especially in today’s rapidly changing labour world”, Prof Grider says.
